Quizplus · Accepted Answer

A KVM Switch allows you to control several physical computers using one monitor, one mouse, and one keyboard.
Key Takeaway - Frequently seen in server rooms, KVMs allow you to control up several computers using one set of input/output devices. Older KVM switches had 4, 8, or 16 sets of two female PS/2 ports and a female VGA port for the incoming connections. Now, USB and DVI connections are not uncommon, and switches can even be found that use Ethernet ports.
