Which item is an input device?

• A. Projector.
• B. Hard drive that stores data.
• C. Keyboard, mouse, scanner, etc provide data to the computer.
• D. Printer that outputs data.

Answer: (C)

An input device is hardware that sends data to the computer from the outside world. The keyboard provides keystrokes, the mouse transmits movement and clicks, and a scanner digitizes documents to feed into the computer. These actions involve actively inputting data for the computer to process. A projector displays the computer’s output on a screen, so it’s an output device. A hard drive stores data for long-term use, so it's a storage device. A printer outputs data as a physical copy, so it’s an output device as well. Therefore, the option that mentions keyboard, mouse, scanner, and similar devices is the best answer because it specifically describes devices that input data into the computer.
