Which device is used to display results produced by a computer?

• A. Output device
• B. Input device
• C. Sensor
• D. Display

Answer: (A)

Think about how computers present results: through an output device. An output device is hardware that converts the computer’s data into something you can perceive, like text or images on a screen, printed pages, or sound from speakers. A monitor or screen is a common example that displays the results visually, while a printer makes a physical copy and speakers emit audio. A display is a specific type of output device—the screen itself—so the broader term that covers all ways to show results is the output device. Input devices (like keyboards and mice) and sensors feed data into the computer rather than showing what it has computed.
