What is an example of an input device?

• A. A monitor
• B. A printer
• C. A keyboard
• D. A speaker

Answer: (C)

A keyboard is an example of an input device because it is specifically designed to allow users to enter data and commands into a computer system. Input devices are essential for interaction between the user and the computer, facilitating the entry of text, numbers, and other commands.

In contrast, a monitor is an output device that displays information processed by the computer, while a printer produces hard copies of documents and is also categorized as an output device. A speaker, similarly, outputs audio signals and is used to playback sound generated by the computer. Therefore, among the listed choices, the keyboard stands out as the device that inputs data into the system.
