KVM Switches

Suppose you have more than one computer in the same room but you do not have enough room for a second monitor. Or, you have a laptop and want to use it with your home computer's keyboard, mouse and monitor, without changing your current setup. The answer lies in a handy device called a KVM switch.

KVM stands for keyboard, video, mouse. The keyboard, video, and mouse set collectively is called a "console." KVM switches allow you to connect a console to more than one computer. You simply connect your console cables to the output jacks of the switch and connect the switch to the connections on your computer that the keyboard mouse and monitor would normally be plugged into. It's that simple.

KVM Switches Let You Switch between Consoles

To switch consoles, you just push a button on the switch and it allows you to use the other console. KVM switches save you money because you won't have to purchase separate keyboards, mice, and monitors for each computer you use. It makes it very easy when one person uses more than one computer at work, for example. They are also useful for server farms with one staff person accessing each computer periodically, one at a time.

When buying KVM switches, it is important to fully understand your needs before you buy anything. Make sure the switch you choose will support your monitor refresh rates and resolution so that the signals are not degraded.
