Which of the following is NOT one of the three common input devices?

• A. Keyboard
• B. Mouse
• C. Printer
• D. Microphone

Answer: (C)

The correct choice is the printer because it is not considered an input device. Input devices are used to enter data into a computer system, allowing users to provide commands or information. The keyboard and mouse are classic examples of input devices, as they enable text entry and pointer control, respectively. Similarly, a microphone serves as an input device that captures audio. In contrast, a printer is an output device that produces a physical copy of digital documents and images. It takes the processed information from the computer and presents it in a tangible form, which is fundamentally different from the role of input devices. This distinction is crucial in understanding how various peripherals interact with a computer system in both input and output functionalities.
