How to connect 2, 4 or 5 computers to one monitor, keyboard and mouse

Messy desk? Dealing with more than one computer and your peripherals are out of control? You're not the only one!

Many people would like to connect 2 or more computers but control those computers with only one monitor, one keyboard and one mouse. The good news is there is an elegant, simple and inexpensive solution - the KVM switch.

KVM stands for keyboard, video and mouse.

There are 2 basic types of KVM switches, PS/2 and USB. PS/2 refers to keyboards and mice that are connected using older cable ends that are round. Mice generally have green plugs and keyboards generally have purple or blue plugs. PS/2 cables and inputs are often found on older computers, mice and keyboards. Many people still insist on using their older components.

USB stands for Universal Serial Bus and these are the cables that most of us are familiar with on modern computers, peripherals, keyboards and mice. The male ends of these cables are flat and rather square.

A basic KVM switch for 2 computers, for either USB or PS/2, currently costs about $25 -$50.00 (US). This isn't anything fancy, but it's simple and it works. Many of these switches also come with a remote control attached making switching between computers a breeze.

KVM switches that control more computers are more costly, but it's certainly easier than dealing with a line of separate computers each with their own monitor, keyboard and mouse.

When space is at a premium, a KVM switch is the way to go.
