KVM Switches (Keyboard Video Mouse)A KVM switch is a device that allows a user to control multiple computers or servers using a single keyboard, monitor, and mouse. This can be useful in a number of different scenarios, such as when a user has multiple computers in a single location, or when a user needs to access multiple servers remotely. KVM switches are commonly used in data centers and other IT environments where there is a need to manage multiple devices from a single console.
