KVM switch (keyboard, video, mouse switch)

A KVM (keyboard, video, mouse) switch is a hardware device that allows a user to control multiple computers from a single keyboard, video display monitor and mouse. KVM switches are often found in data centers where multiple servers are placed in a single rack. By pressing a button on the kvm switch, the administrator can change control from one server to the next. Using a KVM switch can save the administrator the cost of purchasing a dedicated keyboard, monitor and mouse for each computer, save space in the server room and limit cable clutter.
