Which device allows you to use one keyboard, monitor, and mouse for multiple computers?

  1. KVM switch

  2. Router

  3. Monitor splitter

  4. USB hub

The correct answer is: KVM switch

A KVM (Keyboard, Video, Mouse) switch is a device that enables users to control multiple computers using a single keyboard, monitor, and mouse setup. This is particularly useful in environments where space is limited, or where multiple computers need to be managed simultaneously without the need for multiple sets of peripherals. The KVM switch connects to the various computers, allowing the user to switch control between them easily, often with the press of a button or a keyboard shortcut. This helps to streamline workflows and can reduce the clutter that comes with having several separate keyboards and monitors. In contrast, a router is primarily used to manage network traffic and connect devices to the internet, and does not facilitate direct control of multiple computers with a single set of peripherals. A monitor splitter is designed to duplicate the video signal to multiple monitors, but it does not enable control of multiple computers with a single keyboard and mouse. Meanwhile, a USB hub simply expands the number of USB ports available, allowing for more devices to connect to a computer rather than managing multiple computers.
