In computer hardware, a KVM switch provides users with a greater range of device control. KVM is based on three words: Keyboard, Video, and Mouse. The KVM hardware delivers the capability to manage multiple computers, servers or other KVMs by using a single keyboard, monitor or mouse. KVM switches connect computers together as permitted by distance and port availability. Switch specifications tell users the number of devices that can be accessed and controlled. For example, a four-way KVM switch allows for the control of four computers using one set of peripherals. Enterprise-level KVM solutions with remote LAN management are available.

KVM Switches Offering Scalability

More advanced KVM switches are scalable devices that support interconnections using a daisy chain or cascade method. The cascaded or daisy-chained KVM can potentially support more than 500 computers or servers. Each of these computers becomes accessible and controllable by a user on one keyboard. There are KVM devices with 16 or 32 ports for higher density. A rackmount KVM switch enables direct computer connections, while also offering daisy chain architecture to control more than 250 components through one keyboard, mouse and monitor. KVM switch technology in a console is a comprehensive solution that supplies the KVM and the components for control in one unit.

Virtual KVM Computer Software

Software can also act as a virtual KVM. Programs are installed on network computers to generate a virtual keyboard and mouse switch. This switch sets up remote access on multiple computers so a mouse cursor can move across individual monitors.
