Why is the Keyboard an Input Device

The keyboard is an input device because it sends information to the computer rather than receiving information from it. When you press a key, the keyboard transmits a signal to the computer that corresponds to that specific key. The computer then interprets this signal and uses it to display a character on the screen, execute a command, or perform some other action.

In contrast, output devices like monitors and printers receive information from the computer and present it in a human-readable form.

Input devices serve as the gateway for users to interact with digital systems, enabling the transmission of commands, data, and information. Among the array of input devices available, the keyboard stands as a fundamental and indispensable tool. Its role in facilitating communication between users and machines is pivotal, making it a cornerstone of modern computing. Also, read about Is Windows Home or Pro better for gaming
