Adware & Spyware are caught through the regular use of the Internet.
Below are some tips on how you can avoid having spyware installed on your computer without you knowing.
1. Keep Microsoft Windows Updated
Many users are still not quite sure why it is necessary to download software updates on a regular basis.
Security holes in software products are *regularly* discovered, and must be fixed by the software maker, through updates.
Well, in the case of Microsoft windows (your operating system), it's *vital* that you keep it updated, since most attacks take advantage of security flaws that have been already fixed in the latest updates.
Therefore, it is critical that you download these types of updates in order to combat certain loop holes in their security system.
2. Be Wary Of Dubious Software
I apologise for this rather vague piece of advice, but essentially the way to avoid trouble is simple:
*Only* install software downloaded from the maker's site, or from official "mirrors", and not from other places (especially peer-to-peer networks).
You might then say 'well, what if the maker is dodgy?'
My answer would be: 'Sometimes, it is almost impossible to tell if a maker is legitimate or not, and that is part of the risk we take when using the Internet.'
If you are in doubt, you always have the option of asking someone techie or in the know!
Or you can *always* ask me! Send me an email at: mail@spywareremoversolution.com
3. Use An Anti-Spyware Software Product
If you want to be 99.9% safe when using the Internet, the best way is to use an anti-spyware software product which will obliterate all of these problems!
You cannot remove spyware problems with anti-virus software, because the software simply won't detect them. I know I keep saying this, but this is crucial to your understanding.

Your Quick Guide to Printing
by Grant Lithgow
The first thing to consider is whether you want a color or monochrome printer. If you are not printing color or need a printer for photo prints from your digital camera then buying a monochrome printer will be cheaper and probably a better machine for your budget. A monochrome laser printer (or LED printer) will be cheaper but you also need to bear in mind that they tend to only offer a fixed printer resolution and you are unable to manipulate printing options very much if at all. If you are simply printing text however, they are a good workhorse and cheap.
Moving into the field of color printing, the rise of digital photography has in turn led to an increase in photo print quality print capabilities that can be used in the home. If you are looking for photo print quality then you should be looking at a good photo printer and one that has a comprehensive and easy to use photo studio software package for producing effects, eliminating red eye and general editing. You also need to keep a close eye on the costs of the consumables, particularly the printer ink and toner cartridges as these can be very expensive and the manufacturers expect to make their margin from these rather than the hardware. You should probably focus on a high quality ink jet machine rather than a laser printer as the reproduction quality tends to be better, though the differential is being eroded as the technology develops.
A laser printer will probably be the best option if you are a heavy user and printing hundreds of pages of text, typically with a need for a high quality print finish that customers and users expect to have from you. Laser printers also tend to be faster, have a greater printer ink yield and offer a greater degree of reliability than ink jet printers.
Whichever printer type you are going for, you should check a few things from the manufacturer first. Look at the duty cycle, which is the manufacturer's estimate of how many printed pages can be produced in a month of usage. The rule of thumb is to select a printer that has a duty cycle at least three times that of your own estimated printer usage in order to maximize the efficiency of printer use and minimize maintenance.
Another thing to check is the manufacturers estimate for total print volume, which is the manufacturers estimate of the total mileage that the printer is expected to handle. You will find that beyond this anticipated lifespan the warranty will usually be invalidated as the machine become uneconomical to maintain and repair. If you are a business user you should expect a three year life cycle for the printer but this can vary depending on your usage.
Looking at printer speeds, you need to be careful with what they are actually trying to tell you. Often the printer speed is nothing more than a measure of how fast the feeder mechanism can move the sheet of paper through the printer from the paper tray to the output tray. If printing is actually involves this can be significantly different and you need to be sure that you are actually looking at the speed with which the printer actually can print. In this instance you will be looking for the PCW ratings and the better the rating the faster the actual printing speed for a given level of quality.

Cheap New Laptops: Three Of The Best
by Ara Rubyan
I realize that "cheap" is in the eye of the beholder. Not only that -- the laptops in this article might not even be as cheap as something you could get off eBay or even as inexpensive as a refurbished laptop.
But, face it: new laptops are almost always going to be more expensive than the equivalently configured desktop PC because of the need for miniaturization of the components. And laptops have to use different (more expensive) technologies to maximize battery life.
Bottom line: you're going to pay more for a laptop; or you're going to get less laptop for your dollar compared to a desktop PC.
That said, these three laptops -- Sony VAIO, HP Pavilion, and Dell Latitude -- are all solid buys in a range of prices that is very competitive for brand new equipment. And they come from decent companies and offer you a range of features as well.
Let's get started...
Sony VAIO N170GT
This Sony model is that it doesn't have a lot of junky frills on it. It is a clean looking design. It is stylish, too. The screen is very bright. It doesn't get a lot of glare. The speed and performance is okay. In fact, for the price, it's not bad. The battery is good for probably around four hours. Not super, but enough to watch a movie on a plane flight.
On the downside, this laptop uses an older Intel Core Duo processor. It comes with integrated graphics, which means that the performance is not that great. But you're not paying a lot of money for this laptop either. If you're going to install Windows Vista on this machine you're going to want to upgrade the memory.
Overall, this model of Sony's VAIO gives you a good price, but not a really powerful processor. But the laptop looks great. It's very stylish and attractive.
If looks count and you want to save some bucks, this is a great machine. Brand-new, this model costs about $1100 plus tax and shipping.
HP Pavilion DV6205US
This laptop is part of the HP Pavilion DV6000 series. It is designed to appeal to the mass market. It is a very stylish laptop with a shiny finish -- designed to appeal to the same customers who might consider a Sony or an Apple laptop. It's got a series of high-end components and multimedia features at a price that's lower than the comparable Dell laptop.
This laptop has some pretty nice stereo speakers from Altec Lansing. They're located above the controls. But be aware that if you close the top the sound gets can get muffled.
This laptop also has a 1.3 Megapixel WebCam built right in, as well as two microphones.
There is a row of buttons above the keyboard that launches different features like the media player, volume-control and playback. The keys look nice, but they make a really annoying beeping sound when you press them (and you can't really turn that off either).
This laptop weighs a little over 6 pounds -- lighter than the comparable Dell laptop. When you add the AC adapter, it brings the whole thing up to a little over 7 pounds.
The screen is 15.4 inches wide. It has a shiny finish that makes colors very bright and vibrant. It does give it a bit of glare in bright sunlight or next to a window.
The keyboard is very comfortable. The touchpad has an on-off button. This is very cool because it keeps your cursor from flying off in the wrong direction if your hand passes over the touchpad while using an external mouse.
It has a decent number of ports including a FireWire port, a VGA port, S-video and 3 USB 2.0 ports. You also get a microphone jack and two headphone jacks.
As far as processors go, you have a couple of choices. You can do a 1.86 GHz Celeron or a 2.0 GHz Core Duo. This laptop can be configured for up to 2 GB of RAM, and it'll work with hard drives of up to 200 GB in capacity.
Bottom line: it's got lots of entertainment features, you can configure it lots of different ways and it is very affordable. Brand-new out-of-the-box, you can get one for as little as $600-$800 plus tax and shipping.
Dell Latitude D600
The D series laptops from Dell use the Pentium M which comes in 1.3GHz, 1.4GHz, and 1.6GHz speeds--all paired with Intel's new 855PM chipset. You can this laptop with between 128MB - 2GB of fast 266MHz DDR SDRAM. It also comes with a faster 40GB hard drive, or a choice of 20GB, 30GB, and 60GB drives running at slower speed.
It's got a 32MB ATI Mobility Radeon 9000 graphics chip. There are a number of swappable modules for the single internal bay, including CD, DVD, CD-RW, DVD/CD-RW, floppy, a second hard drive, or a second battery.
The average-sized, 14.1-inch screen isn't super. But it comes with a pretty good 1,400x1,050 native resolution. (You can also save a few bucks by opting for the 1,024x768 display instead.)
It's very fast, and it includes an integrated wireless antenna that is of the dual-band type. This means that if you are within range of a Wi-Fi hotspot that runs either "b" or "g" wireless protocols, this laptop will be compatible with either protocol. It also has built-in Bluetooth.
On the downside, this laptop is part of the D-series notebooks for Dell which means it will not be compatible with C-series Dell laptops. This means that if you have a C-series docking station, you're out of luck. And if you have media modules that are for another C-series notebook you'll have the same limitation.
Overall, this is a very thin and light notebook computer at a fantastic price -- $400, plus tax and shipping.
Conclusion
No matter how you define "cheap," these three laptops give you a great value

Buying Discount Laptops Online
By Brian Tallon
Laptops are one of the most useful and popular types of computer available because of their portability, style, high-performance, and flexibility. Having a portable laptop is not only useful for business people that are constantly on the move and students, but they are also becoming common as replacements for home desktops.
Whereas it used to be that laptops were generally slower than desktops, nowadays many makes and models are high-quality and perform just as well as a desktop. However, you can often expect to pay more for a laptop computer than the desktop equivalent.
The advantage of using the internet to buy a computer is that there are usually plenty of discount laptops available from several retailers. These can be typical sales at certain times of the year, clearing old stock, refurbished laptops, or even cheap laptop retailers.
The range of types, makes, and models of laptops available is huge. If you search for a laptop not knowing what you want or how much you are willing to spend you will more than likely spend hours without getting anywhere. Reading laptop reviews and consumer ratings, however, can give you a good idea of what is currently recommended on the market.
Some of the more popular brands include Hewlett Packard, Dell, Toshiba, and Apple, although there several others that you may also want to consider. Sony laptops for example are stylish, include the latest technology, and highly desirable, although you may expect to pay more for a Sony than several other brands.
For discount laptops I highly suggest taking the time to research many computer websites. There are many retailers online that deal specifically in laptops, many of which differ in price and packages that they make available. For example, some retailers may offer extended warranties and accessories just for buying from them.
It used to be that cheap or discounted laptop computers were slow and bulky. More recently as laptop technology has improved even discount laptops are great value for money. You can easily find one with good performance, nice spec, and made by a reliable brand for just a few hundred dollars online.

Choosing And Comparing Cell Phone Plans
by Puripong Koomsin
When choosing a wireless carrier most people fall victim to the lure of the free phone; which you have to admit can sometimes be very hard to resist. But you have to look beyond the free stuff and learn about the details of the plan you are signing up for. The United States is home to over 10 different wireless carriers and their rates vary from state to state. Other than the monthly dues, there are other factors that make a wireless carrier stand out from the rest. Below is a list of a few Wireless carriers in the United States.
* AT&T, formerly Cingular Wireless Cell Phone Plans - it is the largest wireless network in the United States. This company offers a rollover feature. This means that you can rollover unused minutes from one month to another.
* T-Mobile Cell Phone Plans : T-Mobile has the more minutes for the same price than any wireless carrier. T - Mobile plans offer no extra fees for roaming and long distance calls.
* Alltel Cell phone Plans - A feature of the Alltel cell phone plan is that this wireless carrier allows you to choose up to 10 landline or cell phone numbers to call for free. The problem with Alltel is its availability; it is not available in some areas.
* Verizon Wireless Cell Phone Plans -is one of the country's highest rated wireless service providers. Verizon offers its user's unlimited in-Network calls. With Verizon you are most likely to get service from any location.
* Sprint Power Pack Cell Phone Plans - a feature that entices customers to Sprint is its option to allow you to buy add-on minutes; this eliminates the burdensome overage charges you get from other wireless service providers.
* Nextel Cell Phone Plans - A feature unique to Nextel is its Push-to-Talk, which is a walkie-talkie like feature. For most cell phone plans that offer a text messaging feature, the price for receiving a text message is the same for sending one out. You can however get discounts when using text bundles. Another feature offered by wireless carriers is free minutes during off-peak hours or days - usually during nights and weekends. Most of the time Cell phone plans that are over $40 monthly have this feature.
Other than the basics, try looking out and doing the following things before signing up with a wireless carrier: Read the contract clearly, find out how long you will have to stay with the wireless carrier. Most contracts last for 1 to 2 years, and termination before the contract ends requires the customer to pay a certain amount.
Try and consider choosing the same wireless carriers as your family and friends. This will help lessen monthly dues because most wireless carries offer free unlimited calls within their network. Also, be aware of the taxes you are paying. Taxes can add up and take a significant portion of your monthly bill.
Consider everything when choosing a Cell Phone Plan and a Wireless Provider. Make sure that you are getting the most for your money.

How To Secure Your PC, Software And Data
by Chris Schmidt
The role of the personal computer has taken a whole new meaning ever since the introduction of the Internet. There are scores of Internet surfers who use the Internet from shopping to banking to investing and much more and the Internet today, is a buzzing, throbbing center of activity. But there's some bad news - the Internet is also swarming with quite a few elements from the dark side - and they are called hackers and phishers.
Hackers try to break into your computer to steal or corrupt your important data, while phishers try to obtain your personal identification using dubious methods. You have no choice but to protect your computer from these elements and here a few, easy, cost-effective steps you must take to make your computer almost as secure as Fort Knox:
1. Take a backup of important data regularly - preferably, daily. Buy another hard drive for the backup, but do not permanently plug it into your computer. The idea is to keep your backups away from your computer just in case it is hacked into.
2. Always update your operating system. All developers of operating systems (Windows, Apple OS and Linux) regularly release patches and updates when they discover holes in their programs. So, remember to keep the "automatic update" feature on always. Microsoft Tip: Windows users can go to www.windowsupdate.microsoft.com and download the latest updates.
3. Your web browser (Internet Explorer, Opera, Mozilla Firefox, etc.) too must be updated for the same reasons stated above. All you have to do is visit the browser developer's homepage and download the latest version or update. If you are using the Microsoft Office Suite, then you must make it a point to visit www.officeupdate.microsoft.com and update it, as this software suite is a hacker's favorite.
4. Next, install a firewall on your computer. A firewall turns your computer invisible on the Internet and hackers, phishers, virus/Trojan developers, malware and adware cannot break into it. You can visit www.zonealarm.com and download a personal edition, which comes free. However, if your data security needs are critical, then you must consider investing in a 100% hack-proof firewall.
4. Hackers mostly employ Active-X and JavaScript for planting malicious programs into computers. Also, cookies are regularly planted on your computer to track your browsing preferences - but cookies are relatively harmless. To stay away from malicious programs, you need to tweak your web browser's security settings - Set your security setting for the "Internet zone" to High, and for your "trusted sites zone" to Medium-Low.
5. Now, you need virus protection and therefore, need to install anti-virus software. AVG anti-virus is free software that is updated regularly and you can download a personal edition by visiting its developer's website http://www.grisoft.com/.
6. Never ever open mail attachments that come from unknown sources. They are sure to contain a virus or a Trojan. Also, never run a program located at an unknown origin, on a website that does not have a security certificate - such programs will plant a Trojan on your system.
8. The Windows operating system is set to "hide file extensions for known file types". Turning off this option will help you see files with unusual extensions - which, in all probability, will be viruses/Trojans/Keyloggers.
9. When you are working offline, disconnect your computer from the local area network. That way, a hacker will not be able to attack your computer.
10. Build a boot disk just in case a malicious program crashes your system.
11. Finally, you need to install an anti-spyware program. Ad-Aware SE Personal is an award-winning tool that can help you detect and eliminate spyware effectively.

Protecting Yourself Online with Free Web Proxy Servers
by Brian Teeter
Protecting Yourself Online with Free Web Proxy Servers
In recent times, privacy online has become a big issue, making free web proxy servers a viable alternative for many web surfers. Basically, a proxy server conceals your specific Internet address to protect your anonymity online.
Protecting privacy online is a very real concern. For example, many people resent the idea that the government can have access to an individual's online history-- often without needing a warrant. Likewise, many companies, organizations and schools routinely monitor the online history of their computer users. And unfortunately, there are also spammers and online criminals who seek to gain personal information about web surfers for identity theft or other illegal acts.
How does a free web proxy server work?
The word "proxy" means "to go between." This is actually the simplest way of understanding what a proxy server does. Proxy servers act as a filter between your computer and the Internet. The most popular use of this technology is to provide anonymous web surfing from any location in the world.
When using a web proxy server, you are technically not connecting to the Internet; instead, you are connecting to a remote computer or server which is connected to the Internet. Therefore, you are able to surf the Internet "by proxy."
When surfing the net on a free web proxy server, your Internet browser history will reveal only that you have connected to the proxy site, not the actual web sites you have visited. Using a proxy server will also eliminate the problem of web sites depositing so-called "cookies" on your computer.
A "cookie" is a tiny information file that is left behind when you visit a particular web site online. It can contain information about the exact time of your visit, the length of time you were on the site, information about your location, IP address, operating system and other identifying characteristics. "Cookies" can even contain log on and password information, making them a potential security risk if they should fall into the wrong hands.
But using a free web proxy server completely eliminates "cookies" on your computer. Instead, the sites you visit will attempt to deposit "cookies" on the actual proxy server -- not on your computer.
For all of these reasons and more, it can be smart to use a web proxy service to surf the web, and there are many online to choose from. A simple Google or Yahoo search will reveal thousands of free web proxy servers; however, it is important to be aware that the most popular of these free services tend to run very slowly, making for a frustrating web surfing experience.
But if the free web proxy servers are too slow for your taste, there are also paid services that will provide much faster anonymous online browsing. There are many of these available, and most require either a monthly or weekly subscription fee. If protecting your identity and privacy online is a primary concern, paid proxy services can provide peace of mind for a very reasonable cost.
The Internet is a great resource, but unfortunately, it also has its share of disreputable webmasters and spammers. Using free web proxy servers is a great way to keep your private information from falling into the wrong hands.

Should you buy a desktop PC or laptop?
By: Zahir Shah
You really have no choice except of a notebook computer if your job or lifestyle needs plenty of travel every year. Your own notebook computer will help you a lot when you are out of your home or office.
Now-a-days, you can get laptops as powerful as desktop PCs. Laptops are available with high-resolution graphics, CD/DVD recording, large hard drives and even with more features.
However, if you're sitting on the fence and portability is not required as much, go on buying desktop computer with considering the following reasons:
Desktops are more expendable than laptops: - Desktop computers are quite plain easier to expand and upgrade (using USB and FireWire ports), especially the processor and your graphic card, though you can hang plenty of peripherals off a modern laptop.
Desktops are cheaper than laptops: - Desktop computer is even cheaper than a notebook, so if you don’t need it why you are paying so much. Jump to the desktop side of the fence which costs less and suitable for you.
Laptops repairing cost is much more than desktops: - For example, if your sound card fails with any reason you can easily replace it with any inexpensive adapter card. However, when your laptop creates such problem of sound hardware, you must pull out your wallet because you will not be able to fix it yourself, and the whole motherboard inside the unit will must be replaced.
Here we also figure out how to buy these once you made the decision?
Processor: - if you intend that you will use your machine for standard office tasks and internet browsing, does not matter it will do any processor. But if you are a heavy gamer or you need much more power the Intel Core 2 Duo chip is the better one then.
Memory: - As much memory your PC has installed, you would be able to run as much application at once. Upgrading memory in a desktop after you buy the PC is a snap, but actually its good to buy the amount of memory you like preinstalled with the machine.
Motherboards: - A new motherboard would deliver you smooth new technologies that you are missing right now. It would be faster, would be has Second-generation SATA connections, high-definition audio and even a Dual-card graphic. You should keep in mind to check either the motherboard you are buying has two or one USB ports in fronts or not, because of to plug in your USB memory drive and digital audio player etc.
Graphics: - Before going for shopping make sure what kind of Card will work suite in your PC. If you are a serious gamer and can pay as much go on dual-graphics-card. There are two types of cards, the one is removable from the board and the other is permanently soldered on the board. However we would recommend a discrete graphics board for gaming and an integrated graphics for other use.
Sound Card: - for office use you should buy an integrated sound card for your PC, but if you want to use the PC in your home then a dedicated sound card would be the better choice.
Hard Drive: - Its totally depends on you, if you plan on large amount of data, such digital images or multimedia files on your pc, Large capacity hard drive, opportunity to save more data. For normal use simply buy 40 or 80 GB that most of business users use these days.

Laptops Pose Damage To Male Sexual Health
By: mjb
Living the 21st lifestyle would not be complete without electronic gadgets that prove just how much technology has changed the way we live. With the growing popularity of computers, it is no surprise that researchers have embarked on a study to determine the potential damage, if there is any, that frequent use of laptops may cause on a man's sexual health and fertility. Recent findings by the State University of New York experts have shown that men who frequently use laptop computers could be unwittingly damaging their fertility.
A laptop computer, or simply laptop or notebook, is a small mobile computer that usually runs on a single main battery or from an external AC/DC adapter which can charge the battery while also supplying power to the computer itself. This very useful office and entertainment tool is now being examined so that the public may be forewarned about the potential hazards of long-term use.
Researchers found that when a man balances the said equipment it on his lap, it increases the temperature of the scrotum which is known to have a negative effect on sperm production, and may cause scrotal hyperthermia. Since the function of the scrotum is to keep the testes at a temperature slightly lower than that of the rest of the human body, increase in scrotal temperature can damage sperm production and development. Scrotal hyperthermia has been identified as a risk factor for male infertility.
According to Dr. Yefim Sheynkin, lead researcher from the State University of New York at Stony Brook, laptops can reach internal operating temperatures of over 70°C --- a temperature that is harmful to live sperm.
“They are frequently positioned close to the scrotum, and as well as being capable of producing direct local heat, they require the user to sit with his thighs close together to balance the machine, which traps the scrotum between the thighs,” he said.
There are 29 healthy males aged between 21 and 35 who volunteered to be a part of the experiment. Temperature changes to the scrotum caused by laptop use and the different seating positions over one hour time periods were recorded and evaluated. The following results were observed: In order to balance a laptop, a man has to sit with his thighs together. With this posture alone, temperature in the scrotum rose by 2.1°C. When the men used a laptop in this position, the average temperatures increased by 2.6°C. on the left side of the scrotum and 2.8°C. on its right side.
Researchers also say that the body needs to maintain a proper testicular temperature for normal sperm production and development, or what is termed as spermatogenesis, in medical terms. Their studies have not determined the exact frequency and time of heat exposure that is capable of producing reversible or irreversible changes in spermatogenesis. But previous studies made suggest that 1°C above the baseline is the possible minimal thermal gradient. Based on their findings, the repetitive use of a laptop near the proximity of the male pelvic area might cause permanent damage and infertility. Teenage boys and young men are advised to limit their use of laptop computers on their laps until further studies provide more information on this type of thermal exposure.
At the British Fertility Society conference, Dr Allan Pacey, senior lecturer in Andrology at the University of Sheffield, said that it is already a common knowledge that increasing the temperature of the testicles can affect sperm production. He added that, “... worrying about having a laptop on your knees for only an hour can increase the temperature of the scrotum so significantly.” He warned that men who use laptops regularly should be very careful. Further work is needed to see if regular laptop use is a risk factor in male fertility and man's sexual health, in general.

Notebook Battery Life - Tips To Get The Most Out Of Yours
By Michael Paul Jr
Notebook computers. At this point in the 21st century, they have become an indispensable part of many people's everyday lives. From the commuting business executive and the busy college student, we all want to be mobile with our computers. The big drawback of that is the fact that there is not always a plug around when you need one. A notebook computer's battery is its life-blood. Without proper care, your notebook battery could fail much earlier than anticipated. By following a few simple steps, you can expect to get the greatest amount of usage possible out of your notebook battery before a replacement is needed.
1. Upon purchase, charge the battery to full capacity. Whether you have purchased a new computer have purchased a new battery for your laptop, charging it fully as soon as you open the box is the best recommendation. This allows the battery to reach a full capacity before you begin to use it "unplugged". Most batteries come with a partial charge, enough to get you going if you absolutely had to. Giving that battery a full charge when it is brand new will help set the charge capacity for the battery at its highest possible level.
2. Once you reach a full charge, leave the computer plugged in for at least 2 hours. This action lets the battery "rest" at a full charge for a fairly lengthy period of time. At this point, the battery is not drawing power from your wall socket to charge, and it is also not supplying any power to your system. Letting your battery rest for a time after a full charge helps to "lock-in" that full charge capacity.
3. Unplug the computer and drain the battery. It might sound silly, but now that you have gotten that battery to a full charge, you need to drain the power almost completely. Again, this will help determine the charge capacity of the battery. Leave your computer unplugged and use it until you get a warning telling you that the battery is almost completely discharge. Then save whatever you are working on and power the computer down. Plug back into the wall socket for a fresh charge. Then use the computer at your leisure.

Whether you have purchased a new computer have purchased a new battery for your laptop, charging it fully as soon as you open the box is the best recommendation. This allows the battery to reach a full capacity before you begin to use it "unplugged". Most batteries come with a partial charge, enough to get you going if you absolutely had to. Giving that battery a full charge when it is brand new will help set the charge capacity for the battery at its highest possible level.
2. Once you reach a full charge, leave the computer plugged in for at least 2 hours. This action lets the battery "rest" at a full charge for a fairly lengthy period of time. At this point, the battery is not drawing power from your wall socket to charge, and it is also not supplying any power to your system. Letting your battery rest for a time after a full charge helps to "lock-in" that full charge capacity.
3. Unplug the computer and drain the battery. It might sound silly, but now that you have gotten that battery to a full charge, you need to drain the power almost completely. Again, this will help determine the charge capacity of the battery. Leave your computer unplugged and use it until you get a warning telling you that the battery is almost completely discharge. Then save whatever you are working on and power the computer down. Plug back into the wall socket for a fresh charge. Then use the computer at your leisure.

Choosing the Right Notebook Battery
By Tonny Delarosa
There are millions of notebook batteries out there. So it's no surprise that finding the right notebook battery is a nightmare for the everyday computer users. Unless they are willing to spend long hours of research of course...
This article presents important facts about laptop batteries and the various battery technologies available today. The article will help non-technical people in selecting which notebook battery is the right one for them, whether they are just looking for a cheap battery or high-end components such as li-ion rechargeable batteries.
Don't think all laptop batteries are created equal. There is no such things as a generic or universal laptop battery. They are all different and guess what... it is the best interest of the laptop vendors to keep it that way. No, a Dell laptop battery is not the same as an HP laptop battery, and you cannot use the cheap IBM Lion batteries you just bought to replace the Vaio laptop battery of your girlfriend. The shape, specifications, and size of most laptop batteries differ from one model to another, and I'm not even talking about the well-known exceptions such as the flashy Apple batteries or the heavy duty, water-proof, Panasonic toughbook batteries!
All notebook batteries have, however, a few characteristics that are the same:
- The notebook batteries can be recharged an infinite number of times, especially nowadays because they are generally built of li-ion or Nimh;
- The notebook batteries can be pretty pricey, especially for the higher end models such as the HP, 600e IBM, the Compaq laptop batteries, or the Acer replacement battery;
- The notebook batteries can be pretty delicate electronic components: do not be surprised if your battery suddenly drops voltage or the laptop battery won't charge fully;
- The notebook batterys have to be regularly charged and discharged to maintain their battery life.
Let's discuss about the procedure to use when you want to replace your current laptop battery by a new one. The first step is to turn off your laptop pc and remove the power cable from the back of the machine. Turn the laptop down carefully and remove the battery from its slot. A small switch is usually included and pressing the switch will eject the laptop battery pretty easily on most models.
You should then carefully write down the serial and reference number of the battery. These numbers can be pretty confusing because these are long serial numbers that do not mean a thing to most users: they have strange names such as “HP 1739a”, “Dell w1955.” or “Compaq n1020v”....
Armed with this reference number, the second step for you is to decide on three important factors: (i) your budget (are you looking for a refurbished laptop battery, a new one, or maybe a second-hand laptop battery), (ii) the type of battery life you want, and (iii) the brand. You should buy long-life laptop batteries; it is highly recommended. They are only slightly more expensive. But these models are a good investment because there is nothing more frustrating that running out of battery juice in a place where you cannot user your laptop battery charger such as in many airports.

Notebook As A Tool Of Time Management
By: Roberto Sedycias
Notebooks have emerged as a bare essential for the business executives who carry their work along with themselves. Notebooks which are also known as laptops can facilitate the work process thereby saving substantial and valuable time. In short, it is used as tool of time management.
Owning a notebook is a dream of many, but since it is very expensive nobody buys it unless it is indispensable to them. However, some people having shoe-string budget look for a good notebook. They are the ones who need detailed and comprehensive information on notebooks and laptops before they settle for one.
Basically, buying a notebook or laptop largely depends upon the personal choice, specific requirement and social status of a person. Besides, different manufacturers are introducing notebooks of different look with a wide-range of features. However, some notebooks are launched in the market to cater to a particular segment of buyers keeping in mind of their specific needs. Accordingly, these laptops differ in flavor, class and quality.
Let`s take a look at the various types of notebooks that are available in the market today. Keeping various factors in consideration the notebooks can be broadly divided into four major categories, such as:
Budget laptops - Typically, these laptops cost around US$ 1000 to $ 1200.
Mid-range laptops - Notebooks of this category can be found with a price-tag of about US$1200 to $1600.
Ultra-portable laptops - These light-weight laptops ranges from US$1600 to $2200.
Laptops for the people with a class apart. With all the standard and advanced features in these notebooks, they cost above US$2200.
Performance test of laptops:
Notebooks can be tested on the basis of certain benchmarks such as Multimedia content creation 2003 and Business Winston 2002. These tests determine the performance ability of different notebooks with regard to regular productivity applications and multimedia content application.
Similarly, 3D Mark05 and 3D Mark06 are used as standards to measure the gaming and graphic potential of different notebooks.
Likewise, PC Mark05 is taken as a yardstick to test various components of notebooks such as hard-disk general usage, multithreading, web-page rendering, file decryption and 3D pixel shader.
Moreover, the battery back-up and wireless connectivity can be tested using Battery Mark02 and QCheck as the benchmark.
Finally, Vista Compatibility Check can be undertaken to test if the notebooks have Vista-readiness. Under this test, the performance of the laptops is assessed on the basis of Vista drivers and Vista upgradeability.
Features:
When it comes to features, the list seems endless. Some expensive notebooks have the most advanced features such as built-in webcams, fingerprint readers, TPM and so on. So far as the features go, they can be divided into five different categories, such as:
Physical - Screen size and weight of the notebook
Connectivity - Bluetooth version 1/2, infrared, MMC reader, S-Video, DVI port, FireWire. The number and type of USB ports and PCMCIA slots.
Components - Type of optical drives, whether the notebook has a DVD combo, a CD-RW or a multi-recorder DVD-RW. The hard-drive capacity and any additional component such as wireless optical mouse or an MMC adapter.
Software - Software have always been an essential part of the package. These include recovery CDs, driver CDs, OSes, etc.
Protection - All types of protection available in a notebook, be it a finger-print reader, BIOS level HDD protection, touch-pad lock, TPM, or even rescue option available at the time of boot up.
Pricing and Warranty:
All notebooks ranging from $1200 to $4500 offer warranty of 1 year and some laptops have the option of additional extendable warranty.
So, the above discussed comprehensive analysis and performance tests will definitely help those who are planning to buy a laptop.

Notebook Battery Life
Notebook battery life is an important for the mobile computer user. There’s nothing worse than really needing to access you notebook only to have it switch off due to low battery. There are certain things that can help to prolong battery life.
The first thing to consider would be the conditioning of the battery. More namely your charging habits. The worst thing you can do for your notebook battery is always keep it on the charger or charge it while it’s only half full. This will diminish the life of the battery giving you less hours of operating time. The ideal way to charge your notebook battery would be to use it until it is completely dead and then charge it fully.
The second issue to consider would be your usage habits. Using multimedia such as movies and music will kill your battery a lot quicker. Especially doing operations that are CPU intensive. Playing games will diminish your power supply a lot quicker than say, browsing the internet.
There are also different settings that can help preserve your battery life. Windows has different functions for notebooks. For instance you can set your power usage depending on what you are doing. You can set your notebook to act like a desktop if you are near a power supply to get the full performance out of your system. On the other hand you can also set it to use power as efficiently as possible if you are on the move. These setting change things such as the amount of power the CPU uses, the brightness of the screen and so forth.
In the end it’s up-to the individual user. Some notebooks come with the option of a second battery which can double the power your notebook has at your disposal but this is often costly. Also there are more advanced batteries that can be used but again they will cost you extra.

by Christophe Catesson
Since 2005, sales of laptops have displaced those of desktop PCs worldwide. Due a constant drop in price rapid technical improvements and the swift evolution and extension of the WAN technology, notebooks are destined to replace desktops in most areas both professionally and at home.
Notebooks are light computers, which are comfortable to carry, and they have a flat screen and the keyboard is attached to it. Notebooks are operated on battery and they have LCD (liquid crystal display) display. Notebooks are now a days generally used by people engaged in all the fields. The Notebooks have good battery backup, which makes them very handy and convenient. They are not more than 2kg of weight, which makes them very portable. Mostly the notebooks are used by people form all the fields like the students or the businesses men or architectures as well as engineers or teachers etc...

Increasing Notebook Battery Power
by Roberto Sedycias
Depending upon the model, a notebook battery usually lasts from 1 to 8 hours. However, with efficient battery usage, an hour or two of battery power can significantly be increased. You can save battery power by using the built-in battery saving modes and by following good notebook battery-saving practices.
Built-in battery-saving modes are Stand By and Hibernate. In the Stand By mode, open applications are stored in the RAM, the hard disks power down, the monitor switches off, but the processor goes on running. When you again perform some activity of the mouse or the keyboard, then the hard disk powers up, the monitor switches on, and the data from the RAM is activated, restoring your notebook exactly the way you left it.
The Hibernation mode is used when the notebook is left unattended for a long time. The open applications are stored on the hard disk, which subsequently powers down, the monitor turns off, and the processor turns off going in for hibernation. On soft rebooting like a restart or wake up on LAN, the processor turns on, the laptop wakes up, and the same exact settings are restored. Both these modes should be used to conserve battery power. You can preset your preferences in the settings of your notebook, so that in case you doze off, or leave the device for a coffee or a snack, the notebook automatically goes into any one of these power saving modes.
Following battery-saving practices can also save notebook battery power. You should always adjust the monitor controls to suit the room lighting conditions. Dimming the contrast and brightness saves battery power besides providing relief to your eyes. Auto-save and auto-update features of applications start in the background without your knowledge and these should be disabled. External devices consume a lot of battery power, hence the usage of external mice, monitors, keyboards, optical drives, videocam, digital cameras, or any other device connected to the PC Card slot, VGA/ FireWire/ USB port should be avoided.
Increase the RAM memory, if an extra slot is available, as this puts fewer burdens on the hard disk, which consumes a lot of battery power. Avoid multimedia games while you are running your notebook on battery power. Similarly, avoid music or movies. Copy the CD/DVD on the hard disk and play it from there, instead of the optical drive. Disable WiFi and Bluetooth. Built-in wireless cards should also be disabled. Decrease or set to mute the notebook speaker volume. Turn off all preprogrammed scheduled tasks. All unused open applications should be closed. The general guideline is that when your notebook is on battery power, you should perform only such operations, which are the need of the hour. Rest of the applications can be performed, when your notebook is connected to the mains.
Keeping good care of the battery also prolongs its life. To maximize performance of nickel-metal hydride batteries, they have to be completely drained off before they are recharged. However, lithium-ion batteries do not need cycling/ conditioning, and they do not suffer from memory effects. Hence, they need not be fully drained off before recharging. When the notebook is not in use for an extended period, the battery pack should be removed to avoid battery leakage. Before removing the battery pack, you should charge it fully and then remove it, as all kinds of batteries should always be stored in a fully charged state. Do not store your battery pack along with metal parts, as this will short-circuit your battery.
Utilizing the built-in battery saving options and other means, you can significantly add one to three hours more in the total capacity of your notebook battery. Sometimes, in critical situations, like an important meeting, this extra hour of notebook battery power can help you clinch your desired deal.

Laptop Battery Memory
by Frank Vanderlugt
When we buy a laptop, it comes to us in a so called "discharged condition." It needs to be charged before usage. To have the maximum capacity, it is advised that the battery is charged at least 2-3 times. The first time you charge the batteries of the laptop, it would indicate that the charge is complete say after 10-15 mins. This, as indicated by several experts is the normal procedure to charge batteries. All you need to do is to remove the batteries and charge them again. You must always remember that the battery should be fully used before it is charged again. If this is not adhered to, then it shortens the life of the battery. The task of discharging the battery is simple. Run the laptop till such time the battery is fully exhausted or till such time you get a message, "Low battery, kindly recharge."
You must however make sure that you use the battery as frequent as possible. Failing to do so, it is wise to store in a dry and cool place. Do not get alarmed to find the battery becoming warm while it is being charged. Remember, a battery which is charge will for sure lose its charge in the long run, if it is not used. Therefore, it is better to charge the battery even after it is stored.
The so called run-time depends on the need for power by the equipment. For example, notebook computers make the use of monitors and the hard drive exhausts the battery, thereby reducing the run time of the battery.
There are several do's and don't which should be adhered to when it comes to battery performance. You should charge or discharge especially for the first three cycles when it is new. You should make sure that the battery and the contact terminals are clean. Be sure that you do not expose the battery to heat and cold. Make sure you use up the battery as the battery may wear of if it is not used for a longer period of time. You can make use of the accessories which come along with the laptop. Recondition the battery after a specific period.
There are however several don't which also should be kept in mind. You must take good care of the battery and not even drop or play around with it. Avoid putting the plug into the wrong socket. Never try and expose the contents of the cell and they may just be harmful. Make sure you do not expose the battery to external problems like water or moisture. Finally throw the used battery away. It cannot be recycled so make sure you know which trash can it needs to be thrown into.

Notebook Purchase Review
by Roberto Sedycias
In the early nineties few people could image the impact that notebook would have in the computer industry. Its unique portability made the notebook a product in a class by itself. Soon, it became a must-have product, to those who were constantly moving from office, home or school. Nowadays, it is one of the best selling computer hardware items of all times.
With a Notebook, you can carry your work around conveniently, without having to worry about the myriads of wires, hardware and space needed to keep a desktop. Also, you can choose whether to work from office or home. A Notebook is really handy in any situation.
Portability and mobility are the great advantages of having a Notebook, or laptop. In your Internet search prior to buying a Notebook, you will be presented with a great variety and quantity of information. This can be quite bewildering, so you have to know what features you need in a Notebook.
Upgradabeality is an important consideration: the Notebook you choose now may be the one best suited to your current needs; but in future, you may find it necessary to upgrade it. You will not want to invest valuable time and money in purchasing a Notebook which you will have to discard or sell off in the near future, because of what you might feel as the inadequacy of your current one. When you consider upgradabeality, you have to think of memory or RAM, and hard disk space.
The CPU, or Processor, is the engine which will drive your Notebook`s performance. So you should choose the fastest CPU that is available, depending on your budget and on what you will be using the Notebook for. Tasks like word processing, emailing and surfing the Net do not require a fast CPU. But using CPU intensive applications, such as processing spreadsheets or playing games will work better with a fast CPU.
The RAM, or memory is another important feature, and the more memory you have, the better. Your Notebook`s performance will be greatly affected if you do not have sufficient memory. The minimum recommended these days is 1 Gigabyte of memory. Some experts recommend a minimum of 2 Gigabytes. The more memory you have, the better the performance and multitasking you can expect from your Notebook.
The speed and capacity of the hard disk of your Notebook are important, for this is where you will install all your software and your data (documents, database, photos etc). Make sure that you have enough room to store all your information which can be readily accessed. 40 Gigabytes of hard disk space is considered the minimum these days. Consider getting a Notebook with 80 Gigabytes of disk space.
Do note that Apple Notebooks are now using Intel processors, which means that if you have a hard disk with sufficient disk space, you can partition your disk drive and install both Apple Mac software and Windows software, and switch between the two.
You also have to consider the screen of your Notebook, for this is what you are going to be staring at, and you have to be happy with its resolution and size. You will want a crisp, bright screen with good viewing, especially for photos. You can go and look at different screens at a local electronics store, and try to figure out which size and resolution you like best. Just be sure that the screen is an Active Matrix one and not Passive Matrix.
The other features you will be looking at to connect to your Notebook are external devices such as a mouse, printer, portable disk drive, scanner etc. Good luck!

How to buy a laptop battery? How to buy a laptop battery?
When purchasing a battery for your notebook computer, tde first tding a consumer should look for is tde reputability of tde product at mind. If tde product is made by tde manufacturer of your laptop (i.e. Sony, Compaq, Dell, etc), you can usually be sure it is a quality product. However, many manufactures do not actually manufacturer, instead tdey are tde brander of tde product. For example, if you open up a genuine Sony laptop battery, you may find tdat tde power cells inside are actually made by Toshiba, Panasonic, or a similar big name company. Sony in tdis case has just made tde plastic case of tde battery. tdis goes to show tdat tde brand of tde battery you are buying does not necessarily mean tdat tde quality is superior. Many tdird party brands use tde exact same power cells as original manufacturers. Using a tdird party manufacturer is often a good way to go when buying a battery, as tdere are usually many extra benefits. For instance, most tdird party batteries are much lower in price tdan original manufacturers?batteries. Secondly, tdey usually offer a superior warranty, as tdey realize tdat in order to win tde consumer's confidence; tdey must stand behind tdeir product. A one year warranty is a must. Don? buy any battery witd a warranty less tdan one year. Batteries have been known to die early, and a tdree montd warranty could leave you high and dry.

Solar Power Your Wireless Laptop and Go Green
by Michael Beck
Solar power for remote computing is finally catching on. It is working for everyone from the cross-country cyclist and weekend camper, to regular working stiffs that have to rough it on the job.
Many mobile computer users are going "green" with their lappies on the road. Extreme, or remote computing no longer seems too far fetched. Many professionals enjoy rugged recreational activities, but have to stay wired to the job or business.
Solar power is not just a possibility, but could be a necessity for those that go remote. Solar panels are used to collect solar energy for direct use or storage in batteries to power up later.
Here is how solar, or photovoltaic energy is realized from the "How Stuff Works" website. If you are not an electrical engineer or scientist of some sort, don't be surprised if this does make light bulbs go off in your head. You can always come back and do further research on the Internet.
"The solar cells that you see on calculators and satellites are photovoltaic cells or modules (modules are simply a group of cells electrically connected and packaged in one frame). Photovoltaics, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity. Once used almost exclusively in space, photovoltaics are used more and more in less exotic ways. They could even power your house. How do these devices work?
Photovoltaic (PV) cells are made of special materials called semiconductors such as silicon, which is currently the most commonly used. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely. PV cells also all have one or more electric fields that act to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off to use externally. For example, the current can power a calculator. This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce."
To continue, we will discuss the smaller hand held devices for cell phones and PDAs, all the way to powerful self-contained and fully remote commercial solar systems. Here are several links that describe the use of solar power for mobile computers and other wireless devices from the Do-It-Yourself perspective.

DIY Solar System for $180 http://blogs.experience.com/Patrick/2007/01/portable-solar-power-for-1_.html
How To - Laptop Solar Power http://rmowe.home.att.net/photovoltaic.html
Hand Held Solar Kits Solar kits are designed to be self-contained. They combine solar cells, rechargeable batteries, and a wide selection of cables. These won't power a portable laptop yet unless it's a miser on energy, but they will keep you connected with a limitless power supply for your cell phones, Smart phones, PDAs, and smaller devices. As long as the sun is shining, or the batteries are charged up, you will have power.
Many purists will argue anything solar is not really "green", either because it will never be energy positive (will never generate more power than it took to manufacture), or because it has a battery, making it environmentally unfriendly by default.
Arguments aside, at issue for rugged and remote users is a reliable power source, and having some sense of being connected. So, solar charging devices can be considered either as "convenience efficient" or "emergency efficient". Don't take this as a challenge to engineer types that will want to get their slide rules out, just a notation that these solar kits are an honest attempt at the "plus" column for reducing the human carbon footprint. Wider adoption and acceptance of new technology usually results in greater efficiencies.
Two promising examples that have had good reviews are the reasonably affordable products from Solar Style Dot Com, and the pricier Solio Dot Com. Do a search on YouTube and you will find many videos of Solio in action. If it did not work, we would know it by now.
Portable Solar Power Docking Stations
The idea of using solar power in remote situations is nothing new. The question for us is how well, and how fast, a solar power station will power up your notebook or laptop. Other considerations are the size, weight, and portability. You will find many products in this category, but few online reviews that confirm that these products will actually perform as advertised. The best source I have found for honest reviews in this regard is TreeHugger.com.
There are very few winners in the category of a portable solar power docking station to efficiently run a laptop computer. One that does get good reviews on the subject is the "PowerDock System".
Do an online search for PowerDock System, and you will find many retailers and dealers at different price points. So be patient and shop around. Your Mobile Desk Dot Com is the best resource for a complete descriptions of the PowerDock product line. These include from the least expensive to the most expensive: PowerDock Lite, PowerDock Basic. PowerDock Executive, and PowerDock Elite.
Power Dock Systems are relatively expensive, and range in price form a few hundred dollars on up to $450.00. The PowerDock is an attractive product design and weighs in form 5 to 13.5 pounds.
Another potential winner is the Notepower Solar Laptop Charger from Sierra Solar Systems. You will see the Notepower Solar Charger pop up along with the PowerDock in a search engine query for these type of solar products. Plug in the SmartAdapter with the extended 10 foot cord included, and start charging or topping off your computer battery as long as sunshine is available.
Once again, this is not a review recommendation, but the Notepower has had favorable comments by TreeHugger.com and other reliable sources, giving no pause to mention it here. The 3 lb. Notepower is not designed with a storage battery, but the 20-30 watts of power will charge and run most laptop computers, according to the specs.
You may not consider the Notepower as a true solar docking station, but it is an attractive portable solar package for a temporary power solution. Originally priced around $250.00.
Commercial and Military Grade Solar Power Systems
Some of the best remote solar power systems are designed to meet military standards. You could even say that anything designed for military use is pretty much guaranteed to perform. These systems will compliment anything in the fully rugged notebook computer category.
Energy Technologies, Inc. in Ohio, USA makes a wide assortment of military standard power equipment for field use. Things like field deployable inverters, converters, UPS, engine-generators, along with solar power stations with the trade name Tactical Solar Products.
The product features for these Tactical Solar Products include various combinations of charge controllers, power storage batteries, AC/DC power adapters, multiple DC outputs, and a large selection of folding solar panels. The specific product line is the Solar Suitcase I, Solar Suitcase II, Solar Suitcase III, Solar Suitcase IV, along with the folding SolarTacticalPanels.
Solar Suitcases I-IV can charge Lead Acid, Li-Ion, NiCad, NiMH & other types of rechargeable batteries. The nearly bullet proof folding solar collection panels are available from a 15 Watt to a hefty 330 Watt output panel set. This is "green power", but you are out of luck if you prefer a color other than the two camouflage patterns available.
You will have to call ETI for costs, as product pricing is not published on the ETI websites.
Computing Solar Power Wrap-up
We have looked at several of the many possibilities for solar power, and going "green" with remote computing. The possibilities are becoming more reliable and starting to make more economic sense. You can try to go solar and Do-It-Yourself, or for the less technically inclined there is a wide range of retail and commercial applications for sale. We have attempted to highlight a few of the proven DIY options, and find some of the readily available products, and systems from various online reviews.
Here are a few solar power resource websites you may want to keep an eye on: Altapower.com, RadioLabs.com, and CTSolar.com. You are sure to find more now and in the future with your online searches. Amazing products are already available and in the marketplace for solar power options. As energy costs and energy conservation continue to gain interest as mainstream issues, we should see rapid development of solar integrated design features. Soon it may be a standard feature and part of everyday portable computers.
Let's hope solar power catches on with everyone, not just those using rugged notebooks and remote computing,

Technology Innovation in Mobile Telephony
by Paramantapa Dasgupta
"Today we are Mobile". So Simple and so Smart phase. People who are not having even a savings account in a bank or even a credit card, one can find a mobile handset with them. World has seen so many innovations both Technical and Business, but if we club these two together I'm sure it will be a real hard job to find out a faster and smarter innovative example beyond the word called "Mobility". It's just awesome.
This specific segment has shown tremendous growth in both Technology and Marketing innovation and in this small article I'm trying to inscribe the most important Technology Innovations in a chronological way.
A. Pre-Cellular Era: In 1895, Marconi transmitted wireless signals and it gave birth of radio. Till the end of World War I, wireless innovation took place in AM (Amplitude Modulation) technology. Then FM (Frequency Modulation) came to the picture. Till the end of World War II , the technical development in the field of radio and other wireless technologies were done by Government bodies , in different countries. But the birth of "cellular" concept came just after the innovation of "Integrated Circuits".
B. The 1G Era: Analog Cellular: Based on Analog Transmission and launched in early '80s, the 1G networks were for voice communication. The basic concepts came from two key standards, (i) the Nordic NMT and, (ii) the US AMPS. In late '80s, when 1G took its own pace, different standards started getting popularity in different regions, for example, NTT's proprietary standard in Japan, US AMPS in North America, the British Standard (a derivative of US Standard) in Western Europe and NMT standards in Scandinavian countries.
C. The 2G Era: Digital Cellular: In early '90s GSM became mandatory in Europe and it was done by the European Commission. Regional wireless leaders specifically the Nordic vendors Ericsson and Nokia and a couple of another operators held the major market share. Not only they became popular in their respective countries but in a very short span of time, they became Global Giants. And the impact became very strong in late '90s, only in Western Europe GSM caught almost 35% of the worldwide market. In US and APAC, the same thing happened, that was a huge business growth. By the year 2000, in APAC, GSM held almost 60% of the regional market.
D. The 3G Era: Multimedia Cellular: After the super success of 2G Standards, it got a world wide demand for Data Traffic also, along with the Voice Traffic. But initially the basic target was to get a uniform platform for that. Here the European GSM got a tough challenge from US based Qualcomm's CDMA technology. Now all the mobile handset manufacturers got two options, either GSM or CDMA and ultimately the adoption became absolutely regional. The first adoption of 3G could not bring that pace as it was expected the transition from Voice to Data. In Japan , the local leader NTT Do-Co-Mo did the Data Transition in 1999 in their own way.
E. The 4G Era: Towards Wireless Broadband: From 1G to 2G to 3G, the basic intention of all the carriers was to improve and increase the spectrum capacity. Now when we talk or think beyond 3G, it's really very difficult to comment on the 4G standards today. We can only say that the major players in the market are putting their huge efforts to build the base. For example, the technologies like Wi-Fi , WiMax , UWP, ZigBee , Mobile-Fi are nothing but the building blocks for a super powered , never seen Mobile Broadband revolution. The major careers have put endless endeavors to develop 4G, but according to industry specialists, 4G Ear shall be seen after 2010.

"Today we are Mobile". So Simple and so Smart phase. People who are not having even a savings account in a bank or even a credit card, one can find a mobile handset with them. World has seen so many innovations both Technical and Business, but if we club these two together I'm sure it will be a real hard job to find out a faster and smarter innovative example beyond the word called "Mobility". It's just awesome.
This specific segment has shown tremendous growth in both Technology and Marketing innovation and in this small article I'm trying to inscribe the most important Technology Innovations in a chronological way.
A. Pre-Cellular Era: In 1895, Marconi transmitted wireless signals and it gave birth of radio. Till the end of World War I, wireless innovation took place in AM (Amplitude Modulation) technology. Then FM (Frequency Modulation) came to the picture.

Cellular Phone Technology
by Tom Hansen
When choosing a cell phone you need to know the type of service your wireless provider supports. There are two types of wireless cervices still available at this time. They are Analog and Digital.
Analog Service is similar to FM radio in that modulating radio signals carry information such as voice or data. The receiver and transmitter must be tuned to the same frequency within a small band width for the receiver to rebuild the signal, amplify it, and send it to the speaker. There are limitations on the number of channels that can be used making this technology soon to be outlived. Effective February 2008, many wireless providers will be discontinuing support of this service.
Digital Service is a method similar to computers, in that it uses binary code of Os and 1s. Most new wireless phones and networks use digital technology. The analog signal in Digital is converted into binary code and transmitted as a series of on and off transmissions. There are three digital wireless technologies, CDMA, TDMA and GSM and I will explain these three as phones that work with one may not work on another.
TDMA (Time Division Multiple Access) was released in 1994; it uses the frequency bands available to the wireless network and divided them into time slots with each phone user having access to one time slot at regular intervals. In North America TDMA uses both 800 MHz and 1900 MHz bands. Most of the major wireless carriers use TDMA.
CDMA (Code Division Multiple Access) technology dates back to the 1940's, when it was developed for military use because it was resistant to interference from enemy signals. Known as spread spectrum technology this technology was restricted to military use and top secret during World War 2. In the 1980's the commercial use of this technology was realized after a 1976 publication of Spread Spectrum Systems by Robert Dixon was published. Previous publications were classified military reports or narrow subtopics on academic papers. By 1993 CDMA was accepted as a standard and went into operation in 1996. CDMA also exists at both the 800 MHz and 1900 MHz band, and is used by the major carriers.
GSM (Global System for Mobile Communications) is based upon an improved version of TDMA technology. In 1982, a conference in Europe created a digital standard to allow users to roam from country to country in Europe. By 1987, the GSM standard was created based upon both analog and TDMA digital technologies. Using wider 200 kHz channels instead of the 30 kHz channels TDMA used along with other modifications they were able to speed up the bit rate with a more natural sounding voice-compression algorithm. This also enabled GSM to provide such other data services as email, fax, internet browsing, and internet/LAN wireless access. The GSM standard was accepted in the United States in 1995 and is the only phone that can be used around the world. This technology will be the bases of future growth in the wireless phone industry as it offers the multifunction capabilities today's users require.

Overview of Mobile Framework
by Jignesh Padhiyar
Why Mobile Framework is needed?
The need to display content on mobile devices continues to burgeon - especially with the seamless extension of enterprise data onto the small screen. As a result, solutions for shortening the content-to-mobile implementation cycle are on the rise. If you want to take your content mobile, and do it quickly and efficiently, have a look at mobile frameworks.
Purpose of Mobile framework
The purpose of a mobile framework is to utilize a standards-based architecture that leverages existing IT infrastructure and maximizes return on investment. Such a framework is relatively easily deployed and extends enterprise content to mobile users with both good quality and user experience. The purpose of a mobile framework is somewhat different from actual mobile development tools, which are specifically used to develop mobile applications. Mobile frameworks extend existing applications (such as Customer Resource Management (CRM) to mobile workforces and their devices. Just make sure the mobile framework is truly a mobile framework.
Use of Mobile Framework
You're on your way to a pivotal meeting but the flight's been delayed. You need to notify your client, make some last minute adjustments to your presentation, and figure out the fastest route from the airport to their office. In short, you really need to have your office with you. The answer is MOBILIZE YOURSELF! Explains how to maximize the mobility of the technology you have today--and it provides smart answers about the mobile technologies and services you might be considering.
Mobile framework Requirements/Features
This list will help you identify a mobile framework. Usually, a mobile framework will include the following: A graphical development tool that visually maps complex server logic and data to device resident applications
Flexibility for customization and the ability to incorporate new code (MMAPI, .NET, Insignia) Secure access and user identity
An API extension to let other applications "hook" in Enabling of media (video, audio, images) transformation (Java MMAPI, Insignia Mobile Media Framework)
Ability to provide lightweight technology for mobile agent-based distributed computing (Taco Framework)
Ability to provide for content syndication (Jet speed)
Ability to provide content transformation
Agents for device detection
Asynchronous transactional messaging for guaranteed data delivery and integrity Allowance of true mobile client applications with seamless disconnected and real-time operation Mobility is still a new approach to the workplace. Reaching business systems puts special demands and requirements on access, security, and collaboration infrastructure. This can all be reassured with mobile frameworks.
The name MOBILE is derived from the first letter in each of the six categories that make up the framework.The six categories are:
M the need for mobility O the need to improve operations B the need to break business barriers I the need to improve information quality L the need to decrease transaction lag E the need to improve efficiency
Advantages of Mobile Frameworks
So what's important in Mobile Framework is to get the technologies that take you farther and to
# Learn how to choose, customize, and synchronize notebook computers, Pocket PCs, and other mobile devices
# Evaluate your connectivity options--infrared, wired and wireless LANs, cyber cafés, and more
# Make your e-mail, files, corporate data, and favorite Microsoft Office applications road-ready--and secure
# Do more with less gear--get driving directions, enjoy music and video, even manage your stocks and expenses on mobile devices
# Help your company stay agile with sales automation, ERP, and other applications for mobile employees
# Know how to buy accessories and gadgets that aren't just cool, but solve real business problems
Thus Mobile Framework has a large spectrum of different applications, requirements and features. But we Specialties are concentrating on small part of that spectrum and that is "sales automation, ERP, and other applications for mobile employees"

Top Tips For Better Maintaining Laptop Batteries
by Robert Pierre
Neglecting the care and maintenance of your laptop battery will seriously impair the ability to use the laptop when you need it away from an AC power supply. Investing in a little time and effort will repay you many times over by prolonging battery life and laptop use while mobile.
Laptop owners frequently omit to read and care for laptop batteries and make two very simple mistakes. In the first instance they use the laptop battery power in continuous conjunction with the AC power supply. Eventually they find the laptop will not power up when they come to use it. The second instance is to use battery power with no regard to the effect of repeatedly discharging the battery only partially.
What do you do when you try to switch on your laptop and all you get is dead silence? First step: remove the battery and then connect to the AC power supply alone. If the laptop powers up you know you have a problem with the laptop battery. A process known as purging is often enough to resolve the battery issue and we'll show you what to do later on.
Partially discharging the battery repeatedly teaches the battery that it does not need to charge itself fully when AC power is connected. When you come to rely upon battery power and you do not have a full charge, then your use of the laptop when away from an AC power supply is curtailed. The battery "memory" is reduced when incompletely discharged and this produces the shortening effect which is known as "battery fade".
Many laptop owners have experienced battery fade when they eventually come to use their computers on battery power alone. You can deal with this phenomenon quite simply but first you need to establish what type of laptop battery you have in your machine and take the time to review the care instructions issued with the laptop.
Here are some tips for you but you will need to check whether you have a NiCad (Nickel Cadmium) or HiMH (Nickel Metal Hydride) battery for your laptop and check the manufacturers instructions.
The first tip is to ensure that you completely discharge your laptop battery. You do this by powering the laptop up using battery power alone and with the AC power disconnected. Allow the laptop to run the battery down completely until you get the battery low warning. Reconnect the AC power and allow the battery to be recharged from this state, for the period the manufacturer advises for recharge (as long as 12 hours).
The second tip is to purge your batteries. Purging is where you disconnect the AC power completely and also stop the laptops sleep or hibernation feature from being initiated. Allow the laptop to discharge the battery until it has itself powered off due to lack of power. Reconnect the AC power supply but do not power the laptop up and allow the battery to regain a charge for the next 24 hours. If you have NiCad batteries, perform this once a month and for NiMH every three months.
These two simple procedures will ensure that you are able to prolong the life of your laptop battery and make sure you can get the most out of mobile computing. Reading the battery care instructions will take only a few minutes. The return on this simple investment is not simply the money you will need to expend to replace otherwise perfectly good laptop batteries but the enhanced use and productivity to be gained from using your laptop when you need it and wherever you happen to be.

Free Internet Security Software
by Dave Jacobs
There are amazing free internet security software products available in any category imaginable. If you select the proper combination of quality free products you will be provided protection as good as or better than that afforded by the purchased alternatives.
You must realize that there is a wide range in the quality and performance of free software, so you need to stick with products that have been tested and have an established track record or at least have been developed by an organization that has previously proven themselves. It is difficult to tell if most internet security products are performing as expected. For example, if a game is not working properly you will be able to immediately tell because the game will not play correctly. In contrast, if a firewall or antivirus program fail to function properly you may not have any idea until long after your computer has been compromised. This certainly is a risk that few of us can afford to take.
I like to think of internet security as a triangle with the three main categories making up the three corners and the secondary categories lying on the lines of the triangle or within the security triangle. The three corners are antivirus, firewall and antispyware. The differentiation between product classes has begun to blur and there are many combination products especially among those sold commercially. To simplify our discussion and allow us to look at a number of unique free products we will look at them as distinctly unique product classes. There is excellent free software to satisfy our triangle concept with this article focusing on a couple of the top products in each category.
There are about 15 free antivirus products that are worth considering with a few other specialized products that also fit best into this antivirus group. My favorite free antivirus product without question is Comodo Antivirus. Comodo is involved in the high end enterprise area of the internet and decided to provide this antivirus product free to help make all consumers safer while online. The bottom line is that Comodo gets a lot of goodwill and free publicity from making such a great product available free of charge. It is a win-win situation! This antivirus product detects and eliminates viruses from desktops and networks, protects with real-time on access scanning, uses proactive heuristic analysis to intercept unknown threats, has host intrusion detection to block malware before it can run, and provides automatic daily updates of virus definitions. The other free antivirus product that I will touch on here is from PC Tools well known for their Spyware Doctor and also Registry Mechanic. In this case there is also a paid version that has direct customer support and faster updates but the two products themselves function the same whether free or paid. PC Tools Antivirus Free Edition provides world-leading protection, with excellent database updates, OnGuard real-time protection and comprehensive system scanning to ensure your system remains safe and virus free. This product is Vista compatible.
There have been many changes in the category of free firewalls with a number of popular free products no longer available and a few new arrivals to take their place. There are about 15 free firewall software products that I feel are worth considering. The two free firewalls that I prefer are Zone Alarm Free Edition which now is Vista compatible and has been a #1 choice for a number of years. It has proven itself as real winner practically defining the firewall class. The other free firewall I would like to mention is the Comodo Firewall, which like their antivirus software mentioned above, is fully functional yet free. The Zone Alarm Firewall is a reliable but basic product that lacks some of the features of their higher-end retail products. This is not to say that there is any type of reliability or quality issue just that it is feature limited. Comodo's firewall on the other hand is in no way a limited feature product in fact it has some of the most sophisticated features of any firewall free or paid! Many reviewers consider it the best software firewall in existence.
There are almost two dozen good free antispyware products available. One feature of antispyware software compared to antivirus and firewall software is that more than one antispyware product can usually be used at the same time. I currently use Windows Defender from Microsoft, Spybot Search and Destroy and Spyware Terminator all running at the same time. They work fine together on my particular system with no performance hit or other problems.
Picking any one product from each of the three primary groups above should give you a more than adequate triangle of internet security protection.

There are about 15 free antivirus products that are worth considering with a few other specialized products that also fit best into this antivirus group. My favorite free antivirus product without question is Comodo Antivirus. Comodo is involved in the high end enterprise area of the internet and decided to provide this antivirus product free to help make all consumers safer while online. The bottom line is that Comodo gets a lot of goodwill and free publicity from making such a great product available free of charge. It is a win-win situation! This antivirus product detects and eliminates viruses from desktops and networks, protects with real-time on access scanning, uses proactive heuristic analysis to intercept unknown threats, has host intrusion detection to block malware before it can run, and provides automatic daily updates of virus definitions. The other free antivirus product that I will touch on here is from PC Tools well known for their Spyware Doctor and also Registry Mechanic. In this case there is also a paid version that has direct customer support and faster updates but the two products themselves function the same whether free or paid. PC Tools Antivirus Free Edition provides world-leading protection, with excellent database updates, OnGuard real-time protection and comprehensive system scanning to ensure your system remains safe and virus free. This product is Vista compatible.
There have been many changes in the category of free firewalls with a number of popular free products no longer available and a few new arrivals to take their place. There are about 15 free firewall software products that I feel are worth considering. The two free firewalls that I prefer are Zone Alarm Free Edition which now is Vista compatible and has been a #1 choice for a number of years. It has proven itself as real winner practically defining the firewall class. The other free firewall I would like to mention is the Comodo Firewall, which like their antivirus software mentioned above, is fully functional yet free. The Zone Alarm Firewall is a reliable but basic product that lacks some of the features of their higher-end retail products. This is not to say that there is any type of reliability or quality issue just that it is feature limited. Comodo's firewall on the other hand is in no way a limited feature product in fact it has some of the most sophisticated features of any firewall free or paid! Many reviewers consider it the best software firewall in existence.
There are almost two dozen good free antispyware products available. One feature of antispyware software compared to antivirus and firewall software is that more than one antispyware product can usually be used at the same time. I currently use Windows Defender from Microsoft, Spybot Search and Destroy and Spyware Terminator all running at the same time. They work fine together on my particular system with no performance hit or other problems.
Picking any one product from each of the three primary groups above should give you a more than adequate triangle of internet security protection.

POS Hardware Solutions
POS is a short form for point of sale. POS hardware is basically used at trade or retail level, a checkout counter in a shop, or changeable sites where a deal occurs in this type of environment like restaurants, hotels, stadiums, casinos, as well as retail environments. POS hardware uses computers and dedicated workstations that are connected with money records, barcode readers, ocular scanners and magnetic band readers for correctly and right away capturing the business. POS hardware includes label printers, cash drawers, Barcode scanners, pole display, card swiper or reader, POS Monitor, POS Touch Screen and receipt printers. To use POS hardware, retailers need to know about them.
A vital element of POS hardware is the cash drawer. It is used to store Money, credit card receipts and other paperwork. Cash drawers receive a signal from the computer or receipt printer. The cash drawer should be compatible with the rest of the system if purchasing the POS hardware separately. Cash drawers should be strong and survive the steady opening and closing. Pole display is an elective POS hardware. It is a lighted display used to display the transaction totals, sum tendered and to display feature modified messages or to show advertisement.
POS Monitors may be a flat-panel LCD monitor or a standard CRT monitor; the LCD monitor may be more expansive than the standard but takes up less space at the checkout counter. POS Touch Screens are easy and faster to use than traditional keyboards and monitors and save counter space. The keyboards serve as a main POS hardware. Keyboards could differ in complexity and technology. They range in choices from a standard 101-key model like you may have on your home PC to industry-specific POS keyboards. Where special functions are required like Grocery stores and restaurants, only programmable keyboards are used.
Bar code scanners are used at many shops and restaurants for checking out the price of the product. They can be of a different size and technology. Hand-held scanners are the most common in use for the small retailers. Bigger stores with important checkout doings may require an embedded scanner, which mostly can be seen in supermarkets. Barcode scanners read a series of numbers and the barcode, decode the information, and send that information to the computer. Credit card readers or swipers may be included in the POS hardware. The Credit Card Reader is used for credit card reading. In addition to credit and debit cards there are some devices, which can work with gift cards and other loyalty programs, these are called signature capture devices. These devices help in making more efficient transactions and lessen the costs and errors linked with deposit documentation.
Conversely, receipt printers are used to print a documentation of the transaction for the customer. Receipt printers may be a Serial dot-matrix printer or a Thermal receipt printer. Dot matrix printers are normally cheaper than Thermal receipt printers but not as durable. However, Thermal receipt printers are very expansive and are suitable for long use.
