Final answer:
A KVM switch is a hardware device that allows a user to control multiple computers using a single keyboard, video display, and mouse (KVM).
Step-by-step explanation:
A KVM switch is a hardware device that allows a user to control multiple computers using a single keyboard, video display, and mouse (KVM). It enables users to switch between different computers without the need for multiple sets of peripherals. For example, if you have two computers but only one keyboard, monitor, and mouse, you can connect both computers to a KVM switch, and then use the switch to control each computer.
KVM switches are commonly used in settings where multiple computers need to be managed, such as data centers, server rooms, and tech support desks. They are particularly useful for IT professionals and gamers who may need to switch between different machines or systems frequently.
Overall, KVM switches simplify the process of managing multiple computers by reducing the need for additional peripherals and streamlining the switching process.
