A KVM switch is a box where you can connect a number of PCs with a mouse, a keyboard and a monitor. The KVM switch allows you to switch between the various computers or servers with a single click. This means that you are free from moving around on the cables when you switch from one PC to another.
KVM switches are available in many different sizes from 2 PCs to over 16 PCs. They are also available with USB, PS/2, VGA/DVI and with audio connectors.
When purchasing a KVM switch, be sure to check if KVM cables are included.
