KVM Switches

A KVM stands for “Keyboard, Video and Mouse”. A KVM switch is a hardware gadget which helps the user to organize several computers from a single keyboard, video monitor and mouse. Although many computers can be connected to KVM’s only a few computers can really make the most of the secure KVM switch apparatus.

Lately, more devices are being supported with KVM capability allowing firewire and USB devices such as routers and speakers to connect to the KVM. A number of markets prepared KVM’s can also function in reverse i.e. a single PC can be combined with multiple keyboards, monitors and mouse.

Utilization of KVM Switch

However, the usefulness of KVM switches can be fully maximized when there are a number of computers in use, for example in information centers when different servers are in operation – multiple racks being controlled by one keyboard, mouse and monitor.

In this manner, KVM’s help data centers connect to multiple servers as they need, without loss of control. In homes with the aid of KVM switches; keyboards, mouse and monitors of a home PC can be combined with notebooks, tablet PC, PDAs, and Mobiles etc..

Less Expensive to Buy

KVM Switches are some of the cheapest mechanical devices available in the market. These are based on multi-pole switches. They have a rotary knob to select different computers. Typically KVMs allow sharing of 2 to 4 computers, but can join a maximum of 12 machines onto a single switch configuration.

One disadvantage of using mechanical KVMs is that, if a specific computer is not selected by the switch you cannot ‘see’ a computer keyboard or its mouse. Users are also advised that during power failures when a PC reboots for a while KVMs will be not able to detect keyboard and mouse. In the absence of a powerful KVM signal, KVM switches fail to communicate optimally or at their complete capability.
