KVM is an abbreviation of Keyboard Video Mouse. A KVM enables the operation of two or more computers from one keyboard, mouse and monitor. KVMs allow you to switch between the connected computers which is usually by a selected ‘hot key’ on your keyboard or a button on the KVM unit itself. Advanced features on certain units include audio (for speakers/microphone) and USB switching. Check individual product specifications to confirm the specific connections included will meet your requirements.
