Author: When purchasing a computer you must consider not only the quality of the internal components, but also the external ones that make the entire multimedia experience possible.
Computer peripherals, from keyboards to web cams, are an important part of our activities whilst on the computer, if not the most important one, depending on our needs and habits. When you are faced with the situation in which you have to choose peripherals, consider a few things before making your move.
When we buy a printer we must think of our needs before buying it. For instance, if it is meant to be an office printer and it will be used to print out contracts and objectives, then the best choice is an all-in-one printer that can print, scan and have the functions of a fax machine at the same time. If we want a personal printer mostly to get copies of our digital photos then considering a color printer is a must.

Many computer users adopt the ‘it will never happen to me’ policy, but there are a number of computer viruses out there just waiting to infect and destroy the information contained on their hard-drive. This is why companies invented anti-virus software, which is a program that automatically helps to detect the presence of viruses on a computer or in a file before it is opened.
Anyone who spends a considerable amount of time surfing the internet, visiting unfamiliar websites or downloading photographs is at a higher risk for computer viruses than those who do not. Computer viruses are typically attached to word processing documents, computer programs and images which, if downloaded, may instantly affect the computer’s performance.
If a computer virus infects a computer, the owner may immediately lose everything in their computer and may be forced to use the factory restore disk. This CD, which is accompanied by most new computers, will restore the computer to it’s original factory settings.
Anti-virus software is quite affordable considering it’s wealth of use. Without it, computer users are at constant risk for computer viruses. Anti-virus software can generally be found at any computer manufacturer’s website, retail store’s electronic department or online at many retailers selling computers.
Anyone who suspects that their computer may be infected with a virus should refrain from sending any e-mail messages or uploading photos to family or friends. Otherwise, the virus may spread to infect their computers as well.

Learn how to hold the computer mouse:
Hold the sides of the mouse with your thumb on one side and ring finger or pinkie, which ever feels more comfortable to you, on the other side. Your index finger goes on the left button and your middle finger on the right button. (Some computer mice only have one button, some have several, some have a wheel which you can use your middle finger to depress the wheel then turn it up or down to scroll pages very quickly or slow depending on how quickly you turn the wheel. Personally I love the wheel and would not have a mouse without it!) When you are told to ‘click’ use the button under your index finger, or the left button.
Learn how to move the computer mouse:
Slowly slide the mouse around on the mouse pad. See what happens to the arrow on the screen as you slide it around.
Do you need a mouse pad:
You should have a mouse pad under your mouse, (although the new optic mice do not require one). You will have an array of choices when purchasing a mouse pad; find the one that is comfortable for you. Rest your hand on the mouse pad or desk and move it slowly, there is no need to lift the mouse off the mouse pad unless you run out of room, then you just lift it up and reposition where needed. You don’t need to move the mouse to the left or right, simply slide it left or right with the buttons still facing away from you.

The motherboard is the heart of any computer. It is that big flat board inside the computer that everything is connected to. It performs the role directing information and connecting components. A motherboard is often overlooked when choosing components. This is a scary thought as the motherboard determines system performance as much as every other component.
Choosing the right motherboard does not have to be a problem, even though there is a lot to consider. We will start off with the larger parts and move onto the things that are less essential.
Firstly is the socket type. The socket is where the processor (CPU) connects to the motherboard. There is no compatiblility between sockets, so it has to be the right one. The socket connection needs to match the connection of the processor you have or the one you intend to buy for the computer.
Most older Intel Pentium 4s utilize socket 478. Newer ones use socket 775. AMD chips utilised socket A for a long time, but now the AMD Athlon 64 series and Semprons use socket 939. Just check with someone as to what yours or your intended one will have.
Your choice of chip will have a lot to do with your needs, but choosing one with an up to date socket type will ensure slightly longer motherboard life as you can upgrade the chip for a while.
