Which of the following is an example of an input device?

Question

BlackTom AI · Accepted Answer

An input device is defined as hardware that allows a user to feed data and commands into a computer or other system. Keyboard input falls squarely into this category because it enables users to type letters, numbers, and control signals that the system interprets for processing, commands, and data entry.
In this question, the available answer demonstrates an example of an input device by listing keyboard functionality as the input mechanism. By contrast, devices like monitors or printers serve as output devices, displaying results or producing tangible copies rather than sending data into the system; this helps illustrate the distinction between input and output roles.
Since the provided options field is empty, we cannot contrast keyboard against other potential distractors (for instance, mouse, scanner, microphone, or speakers) within the same item. Nevertheless, the core criterion remains: an input device accepts user input to be processed by the computer rather than producing output on its own.
If you encounter similar questions in the future, remember to verify whether the device’s primary role is to supply data or signals to the system (input) versus presenting results or feedback from the system (output).
