The keyboard is the main input peripheral used by all computers. The keyboard allows for user input and interaction with the computer. Much like many typewriters the keyboard has all the letters of the alphabet, numbers 0 - 9 and additional special operational keys, e.g. for adjusting the volume or going to your inbox directly. There are three different connection types:- USB is the most modern. You can recognize it by the rectangular connector.- PS/2 connectors are round. This type of connection is fairly commonly used by PC's.- Bluetooth is another modern (wireless) connection method.
A keyboard, video, mouse (KVM) switch allows you to connect multiple computers to one keyboard, mouse, and display. You can switch between the different computers by a simple keystroke, without (un)plugging a single wire.

A mouse pad is very useful when you still have a mouse with a ball in it. It provides better grip for the ball on the surface, so you can work more conveniently with your mouse. For the newer optical and laser mice it is important to have an entirely flat surface to work on. Not all mouse pads provide this, so have a close look at the surface of the pad before buying it if you intend to use it with the latter kind.

To prevent Repetited Strain Injury (RSI), a painful, numb feeling in your arm(s), wrist(s) and/or hands(s) during and after working with a computer for a prolonged period of time, it is important to have an ergonomical posture while working. A wrist rest for use with your mouse prevents flexion of the wrist, thus reducing the risk of getting a so called 'mouse wrist', RSI in the wrist. A wrist rest for use with a keyboard is not intended for resting your wrist on while working. Use it only for during breaks, to prevent your wrists from unncessary strain.
