KVM is short for keyboard, video, mouse switch, a hardware device that enables a single keyboard, video monitor and mouse to control more than one computer one at a time.

KVM switches are popular among users who have upgraded their home PC systems and want to still use their old computers but do not want to invest in a second keyboard, monitor and mouse. KVM switches are also used by business to save money when one person uses more than one computer and in server farms where it is only necessary to periodically access each separate server in the farm one at a time.
