Which of the following devices can both input and output data?

• A. Webcam
• B. Printer
• C. Microphone
• D. Touchscreen Monitor

Answer: (D)

A touchscreen monitor can both input and output data, which makes it a versatile device in computing environments. As an output device, it displays visual information such as graphics, videos, and text, similar to a standard monitor. Meanwhile, it can also serve as an input device; users can interact directly with the screen through touch gestures like tapping, swiping, or dragging. This dual functionality allows for a more intuitive user interface, making touchscreen monitors popular in various applications, from smartphones to interactive kiosks and tablets. Other options listed each have a singular function: a webcam is primarily an input device capturing video, a printer is solely an output device producing hard copies of documents, and a microphone is an input device that captures audio. None of these can perform the dual role that a touchscreen monitor can.
