How does a KVM Switch work?


A KVM switch pushes multiple video and peripheral signals and produces a single output to a single keyboard, video or mouse, allowing for quick access to several computers and data sources.


Some KVM switches allow users to alternate audio and USB devices between computers and many are designed for connections of up to thousands of users and servers controlled from a single console.


When are KVM Switches used?


Control multiple computers: KVM switches are commonly used in environments when you need to control multiple computers like in a data centre. With a single switch, the administrator can alternate access from one computer to another.


Multi-user computer control: by using a KVM Matrix switch, multiple users can control one to many shared computers, enabling cross-functional access to data.


Control of Multiple Operating Systems: KVM switches enable users to switch across multiple operating systems such as Microsoft Windows, Mac, Linux
