Which of the following is an input device?

• A. Monitor
• B. Printer
• C. Speaker
• D. Mouse

Answer: (D)

Input devices are hardware that let you feed data into a computer by capturing your actions or signals. A mouse fits this role because moving it and clicking its buttons are turned into digital signals that control the computer’s cursor and execute commands. In contrast, a monitor is used to display the computer’s output, a printer produces a physical copy of data, and a speaker outputs audio generated by the computer. So, among these options, the mouse is the device that serves as input.
