Which of these is not an input device?

Explanation:
An input device is any hardware that takes data from you and sends it to the computer. The keyboard converts keystrokes into digital data, the mouse translates movements and clicks into commands, and the scanner converts physical documents into digital information. The cathode ray tube, by contrast, is a display technology used to show the computer’s output. It doesn’t capture data from you to feed into the computer, so it isn’t an input device.
