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

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

Answer: (C)

A mouse is an example of an input device because it allows users to interact with a computer by sending data to the system. Input devices are essential for entering commands and information, and the mouse specifically enables pointing, clicking, and dragging, which are integral to navigating graphical user interfaces. This interaction is necessary for tasks such as selecting files, opening applications, and manipulating objects on the screen. In contrast, a printer and a speaker are output devices, as they display or produce information rather than receive and send data to the computer. A monitor is also an output device because it visually represents data and information processed by the computer. Thus, the distinction lies in the function these devices serve within the computing environment—input devices facilitate data entry, while output devices present processed data to the user.
