Which of the following is NOT an input device?

• A. Mouse
• B. Keyboard
• C. Scanner
• D. Monitor

Answer: (D)

The main idea is distinguishing input devices, which bring data into the computer, from devices that display information. An input device is something you interact with to send data: a mouse lets you move a cursor, a keyboard lets you type, and a scanner converts a physical document into digital data for the computer. A monitor, in contrast, is used to display information produced by the computer, so it serves as an output device. Because it doesn’t take data from you into the computer, it’s not an input device. (Note: some screens can be touch-enabled and act as both input and output, but a standard monitor is considered output.)
