Which device is primarily used to input data into a computer?

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

Answer: (B)

This question tests understanding of input versus output devices. An input device is used to send data into a computer for processing—keyboard, mouse, microphone, and scanner are typical examples. In contrast, a monitor is an output device that displays data from the computer, not inputs it. A sensor also provides data to a computer, but the broad, standard term for devices that feed data into a computer is an input device. So the best description for a device primarily used to input data is an input device.
