A KVM Switch is a hardware device which multiple computers can be controlled using a single keyboard, video monitor and a mouse. Since multiple computers can be controlled via a single keyboard, mouse and monitor, it eliminates unnecessary cable clutter and saves overall space. These switches reduce the amount of hardware needed to control multiple servers throughout your data center. These are often called out of band solutions as they operate outside the main network. They help in transmitting information instantly and in real time.

Available in many shapes, sizes and designs, the KVM Switches work on the simple principle of plug and play. These KVM Switches can directly be used to work and don not require any software to be installed to work properly, so saves you from technical vibes if you have any. They typically can be used to connect a number of computers ranging between 2 and 32, but a key feature of these switches is the ability to be daisy chained to control a larger number of computers using a single set of keyboard, monitor and mouse if the situation demands so. These switches support most operating systems and control is done with just the press of a button or keyboard commands, allowing a user to move from computer to computer effortlessly. Administration of the KVM switch is performed through the built-in OSD function. These devices are also available in various types such as the PS2 KVM switch, USB KVM Switch, DVI KVM switch, KVM over IP, IP KVM Matrix switch and the CAT5 KVM switch.

These devices can also be classified into analog or digital depending on their connection type and are available with audio and mic options. Secure management of information can be accomplished with these devices which are also useful for working more efficiently and saving time and money. In data centers where network administrators use these switches to control servers, rack mount switches are often used. The KVM Switch is becoming increasingly popular in data centers and server rooms throughout large and small industrial, commercial, shopping complexes and government environments.
