ITPEC FE Morning April 2018 Question 11

Printer — it takes data from the computer and puts it on paper, so data flows out of the computer.

Classify a device by the direction of the data: an input device turns something from the outside world into data for the computer; an output device presents the computer's data to people or the outside world. Displays, printers and speakers are output devices.

Answer (c)

Why not others:

• •(a) Camera — captures images and sends them into the computer, so it is an input device
• •(b) Mouse — sends pointer movements and clicks into the computer, an input device
• •(d) Scanner — digitises paper documents and images into the computer, an input device

Key rule: Ask which way the data flows: into the computer makes an input device, out of it an output device.
