The average computer user reaches for the mouse multiple times each hour throughout the course of the day. Improper mouse positioning can lead to pain and even injury in the wrist and arm. Take the time to evaluate your mouse usage. These five guidelines can help protect you as you use your computer mouse.
1. Optimize your mouse location. This is one of the most important solutions for comfortable mouse use. When using a mouse, you need to sit in a natural position, with arms relaxed at your side and your mousing hand raised only slightly higher than your elbow. This placement normally requires a separate mouse platform. If using a flat platform, this will place the mouse approximately one to two inches above the number pad on a normal size keyboard. Using a downward sloping platform, place it to the side of your keyboard, as closely at it will fit. Never reach up to a desk or out to the side for your mouse.
2. Hold your mouse loosely in your hand. In addition to the correct position, remember to use a light touch with your mouse. Gripping too tightly will cause strain in your arm and hand.
3. Move your mouse from the elbow, not from the wrist. The wrist should be held in a straight line with your arm, minimizing wrist movement. Any bending of the wrist can trigger tendon damage. All mouse movement should require the movement of the entire lower arm, pivoting only at the elbow. Be sure you don't restrict arm movement through improper arm rests or hand pads.
4. Protect your wrists from surface pressure. Whether typing or using a mouse, your wrists need to remain free of surface contact pressure. Instead, the base of your palms should bear the weight of your hands to keep pressure off the carpal tunnel area in the wrist.
5. Consider the shape of your mouse. A mouse that properly fits your hand can reduce wrist extension. Take the time to handle and use several different ergonomic mice. The best mouse size and shape for you is one that promotes good wrist position and encourages movement from the elbow.
The advances in ergonomics allow people to minimize the strain caused by extended computer use. As computer operation becomes more and more dependent on the mouse, users need to learn how to protect themselves from improper placement or posture. A good mouse will encourage correct posture and hand position, eliminating pressure to the wrist. Finding the best ergonomic ergonomic mouse for your hand shape and size can lower your risk of pain and injury.

Spammer? Me?
Here's a scary thought for you; you might be a spammer and not even know it. Do you get a lot of forwards in your email? You know, the things that say "Forward me to 10 people and you will get everything you ever wished for in life", or, similarly, cute little messages or pictures that have been goodness only knows how many places before they reached your inbox? Of course you do. Forwards are all over the internet. But here's the real question: did you forward them on to the people in your address book? Yes?
SPAMMER! Unsolicited forwards are no different from any other unsolicited email, except in one respect: you usually get them from people you know, which makes it harder to ask them to stop. And when you've recieved an email, the temptation to click the little "Forward" button--especially if it's a cute email!--is pretty tempting. But stop. Don't do it! Many people are annoyed and irritated by forwards, and sending them is, quite frankly, totally rude.
So what can you do if you keep getting forwards you don't want? First of all, send a polite email to everyone in your address book, something along the lines of "Dear Friends, No matter how cute though they are, forwards really annoy me. Please don't include me in the list when you send them." Just sending that email out got rid of about 95% of the forwards that used to show up in my inbox.
So what about people who continue to send you forwards? Sometimes a polite email addressed specifically to them will take care of the problem--just be sure to keep it polite!--and sometimes it won't. Most mail services allow you to use filters; you can, if you want, filter all email from their address into a separate folder and then ignore it or only check it periodically. As an extreme measure, you can block them completely.
Forwards are no better than spam, and people shouldn't have to deal with them. So remember that, next time your finger is poised over that tempting little button!

Getting to Know Your Computer Hardware
Hardware talk can be pretty boring, but it's a necessary evil sometimes. For those of us who are kind of new to the world of computer hardware, a nice little mini lesson could come in handy to understand what a ROM and a RAM is. So in the best generic terms possible, we will run that down for you.
Your computer is basically made up of several components and to help you understand what each one does, how about be compare them to the human body? I know, this sounds weird, but if you bear with me, I think we can make this work on out for us.
First let's start with the brain of the whole system; the processor. The processor, like the brain tells the rest of the system what to do. Without the processor, all the cool software and hardware you own is useless. The CPU or Central Processing Unit, is definitely the central part of your computer hardware body.
Next we have RAM, which stands for Random Access memory. These are the hands that carry out everything you have to do. Some would say that this is more like what you have learned, your physical memory. Indeed it could be called that, but the idea is that the more RAM you have the more processes you can have running at one time.
You CDROM, CDRW and DVDROM are all considered external drives. This is the cool coffee tray that came with your PC. You could consider this your feet. They will take you places your mind and hands can't go and then away again. ROM stands for Read Only Memory, so it doesn't reside on your hard drive.
Your hard drive is everything you have learned all stored in one spot for you to access whenever you need to. All kinds of functions are on this bad boy, from software you are aware of to "involuntary functions" you PC needs to continue to operate. These devices spin at different speed and can hold different amounts of information. How much information depends on the size of the hard drive. Obviously the larger the drive space, the more can be stored on it. This is a good thing to remember.
You power supply is exactly what the name says. This is what powers your computer. In some ways this is the heart of your system. It's arteries are the power cables going throughout the inside of your tower providing lots and lots of power to your parts that need it. It powers all of your devices and keeps them running without bogging down. If your power supply stops working then your system is dead. A transplant will most likely be needed.
With any kind of luck, my simple explanation of the computer hardware will help you understand how your computer works. For the seriously technically minded, I apologize. For everyone else, well, let's just keep this system between you and I, shall we?

Four Popular Uses For USB Flash Memory
One the most widely used inventions of the past 20 years are the ubiquitous USB Flash Memory sticks. Variously known as Jump Drives, Thumb Drives, Memory Sticks, and many other names, these portable memory devices are to be found everywhere.
The most common use is with PC's and Laptops for storing and transferring files, and they are not only to be found in the Computer Science or Engineering departments. There are probably very few college students today, regardless of their major, that do not own at least one such device.
Memory cards using the same technology are also widely used in digital cameras. The large capacity is what allows hundreds of pictures to be stored before it is necessary to download the images and clear the memory.
Another very popular use for USB drives is as a give-away at trade shows. Promotional flash drives are a welcome and useful item, and much more functional than an emblazoned key chain or desk calendar.
This product has seen an explosion in capacity and a great reduction in price in recent years. When they were first introduced in the late 1980's flash drives could only store a few megabytes of data, and that data came with a respectable price tag. It is now quite common to find devices with 16 gigabytes of memory for under $80.
It is a key component of the popular MP3 players, as well as cellular phones, ATM's, and just about any device that uses upgradeable software, known as firmware.
Look for there to be more uses for this type of memory in the near future. As the reliability increases and cost decreases, they may replace hard drives in some applications.
Christopher W. Smith has been publishing informational articles on various topics for several years.
Benefits of the USB flash drive, and information about other memory USB devices can be found at Chris's latest website, www.MemoryUSB.net.

How to Buy the Right Computer Monitors
Choosing a suitable computer monitor involves careful consideration of many important factors. It all depends on the work to be carried out in the system. If it is intended only for basic purposes like browsing the internet or sending emails, a standard product will be sufficient. Those who are acquainted with the computer will be able to know the significance of many a feature associated with the monitor. But all those who are shopping for monitors are not fully conversant with the working of the system. It is therefore necessary for them to rely upon skilled computer users or dealers who are reliable in this respect.
At the outset the consumer should decide about the size of the monitor. For basic uses it can be about 19 inches or even smaller. The size of the monitor depends on two factors. One is the space available and the second is the budget allotted. If it is intended for gaming or graphic designing larger ones are required. Professionals who are engaged in web designing etc may also require larger monitors which can offer excellent color accuracy.
Conventional cathode ray tube (CRT) and modern liquid crystal display (LCD) monitors are available in the markets. Even though LCD is now very popular and preferred by many consumers, professionals choose only CRT monitors for certain specific tasks like graphic designing. Again, CRT monitors are considerably cheaper and low end users and even students choose them because of the cost benefit. Notwithstanding the cost advantage CRT cannot equate itself with LCD when quality of output is taken into account. Another characteristic that defers from CRT is that LCD monitors have a native resolution. As a result of this the LCD monitors are capable of offering displays at lower or higher resolutions than it is set for.
Large LCD monitors with higher resolutions can produce crisp or sharp images but they require expensive video cards. Widescreen LCD monitors are considered as the best options for those who want to watch movies in the original format. In this context it is better to understand the difference between the computer monitor and the television screen. When LCD screens are incorporated in television, inbuilt tuner and speakers are to be provided. Computer monitor is only a screen sans the above accessories. In the early stages of its introduction, LCD monitors were used only portable units like laptops as they are expensive. But now that the prices have declined the sleek and thin LCD and Plasma screens are much sought after products.
An important factor to be considered while shopping for computer monitors is its compatibility with the system. This aspect is more relevant when the consumer wants to replace the existing monitor with a new LCD. LCD digital monitor requires video card with digital video interface to make it compatible with the existing system. Some other technical specifications like dot pitch and stripe pitch are also relevant for excellent output. It is better for shoppers to consult computer professionals while buying LCD monitor which is an expensive product.
Internet is a good source to learn about the basics as well as some of the complicated technicalities regarding the monitors. It is better to go for reputed branded products which will carry warranty and after sale service. Innovative products are being introduced in the markets by leading manufacturing companies. Even though such branded products tend to be more expensive, they will be reliable and result oriented.

The Wireless Office
Wireless networking can add a lot of flexibility and ease to your office or workspace. The convenience of wireless printing makes daily document management tasks simpler for either a small home office or a larger, more traditional office setting with multiple employees. Many offices have multiple computers - desktops, laptops and personal smart-phones or netbooks. Being able to wirelessly print documents from multiple sources allows the users to increase their productivity and work in a streamlined environment.
Wireless printers, when networked properly, allows multiple users to send a command to print from a number of different networked sources. For example, a person in a back office and an employee on the front sales floor can both send a command, wirelessly, to a printer in a central location. There are no wires traveling throughout the walls or taped to the floor, because wireless technology sends these signals through a secure Wi-Fi network.
Without the wires, your office or home office becomes much cleaner and people are less likely to be injured by tripping over wires. Furthermore, you won't have to worry about the multitude of wires attached to your computer. Without a printer being physically plugged into your computer, you free up USB ports for other computer peripherals. Laptops can be used anywhere within the range of your network's Wi-Fi signal and conveniently send documents to be printed in one central location.
Wireless printers can save your office money. If you currently have individual printers for each computer user, you're spending a lot of money on ink or toner - not to mention printer maintenance. Using one centralized wireless printer significantly cuts down on the money you spend on maintenance and upkeep, as well as energy bills and ink/toner usage.
Wireless technology is constantly evolving. Today, it is possible for some digital cameras to wirelessly find a printer and send photos to it for printing. Other media devices can also wirelessly connect to your printer, giving your home or office a clean, modern appearance and simple, easy-to use wireless networking. If you ever decide you need to move your printer or your computer, you won't have to worry about the cables and making sure they can be ran correctly. All you need is the power cable to have a wall outlet. The network connects your PC to your printer through wireless technology.
There are different standards for wireless networks, the most common being wireless Ethernet (802.11a, b, g, or n). Another wireless option is Bluetooth, but that has a more limited range. Wireless printers have become very popular in the past few years as more and more people discover the benefits of having a clean, streamlined work environment and Wi-Fi connections become more commonplace. The price of wireless printers has dropped, making them a wise economical choice for your home or office.
