Which device allows sharing keyboard, video, and mouse between multiple computers?

• A. Router
• B. KVM switch
• C. Hub
• D. Modem

Answer: (B)

A KVM switch, which stands for Keyboard, Video, and Mouse switch, is a device designed to control multiple computers from a single keyboard, video monitor, and mouse setup. By enabling users to switch among different computers without needing to physically disconnect and reconnect peripherals for each machine, a KVM switch streamlines the management of multiple systems. This is particularly useful in environments like server rooms or workplaces where space is limited or where efficiency is key. The functionality of a KVM switch enhances productivity and reduces clutter, allowing a user to easily toggle between systems with a simple keypress or button. This control method is particularly advantageous in situations where administrators need to monitor several servers or workstations simultaneously. In contrast, other devices like routers, hubs, and modems serve different roles within a network. Routers handle data traffic between networks, hubs connect multiple devices in a local area network without any intelligent data handling, and modems convert signals for internet communication. None of these devices provide the specific capability to share keyboard, video, and mouse inputs across multiple computers like a KVM switch does.
