Section A: Quick Questions

B — An output device presents the results of processing to the user.

A — A monitor

A — A projector

B — They turn processed data into sound you can hear.

A — A printer

Section B: Match the Pairs

monitor → An output device that displays the results of processing as pictures and text on a screen

speakers → An output device that plays the results of processing as sound for people in the room to hear

A device that turns processed data into a printed copy on paper → printer

A screen that is both an input and an output device because it shows results and senses touch → touchscreen

A keyboard is an output device because it shows results to the user. → A keyboard is an input device. It sends data into the computer. It does not present results. A monitor or printer is an output device.

Headphones are used to type in data for the computer to process. → Headphones are an output device. They play sound from the computer so only the user hears it. They do not send data in.

Section C: Definitions

output device — A piece of hardware that shows or gives the results of processing to the user, such as a monitor, projector, speakers, headphones or printer.

Section D: Fill in the Blanks

input -> process -> output

headphones.play(sound)

printer.print(document)

touchscreen is input and output

projector.show(slides, wall)

Section E: Spot the Error

C — A comma is missing between "plays" and sound. Items inside print() must be separated by commas: print(device, "plays", sound).

D — Python is case-sensitive, so Print with a capital P is not a real function. It should be print(copies, doc, output).

C — The function call is missing its closing bracket. It should be display("monitor", "photo").

D — The variable was created as size with a lowercase s, and Python is case-sensitive. Size does not exist, so it should be print("Shows on", size).

A — A keyboard is an input device, not an output device, so it should not be in the list of outputs. Use an output device such as "screen".
