Using multiple computers in a restricted area can be tricky as they often need their own peripheral devices directly attached, such as a keyboard, monitor, and mouse – even though these devices may be used rarely. Buying multiple devices can get expensive, the running costs can be high and they take up a lot of space.

A Keyboard, Video and Mouse (KVM) switch can help alleviate this problem by providing a central hub into which extension cables can be run out to each participating computer for various peripherals but commonly the keyboard, video display and mouse. A single central keyboard, video display and mouse can then be used and the computer to use chosen by some selection mechanism. Think of it as being a bit similar to one of those remote controllers that can talk to your TV, DVD and Satellite box.

Many KVM switches are clever enough to effectively fool the other computers into thinking something is actually attached (when they are not in use) so the computers do not get confused. More recent KVM switches can also link up USB ports, sound and can utilise the network to avoid the need for a physically connected central keyboard, mouse and video display.
