Answer Key

Devices that are both input and output

Section A: Quick Questions

B — Both an input device and an output device

A — Sensing your tap or swipe

B — Showing the picture you see

A — Your swipe on the screen

A — Both input and output

Section B: Match the Pairs

touchscreen → A screen that senses your tap or swipe (input) and also shows the picture (output)

headset → A device with a microphone (input) and speakers (output) in one

A game controller that vibrates is an input device when you press buttons and an output device when it buzzes → controller.vibrate()

A touchscreen takes a tap or swipe in as input, then shows a picture out as output → tap(button) -> show(picture)

touchscreen = input device only → A touchscreen is not only an input device. It also shows the picture, so it is an output device too.

headset = output device only (speakers) → A headset also has a microphone, which is input, so it is both input and output, not output only.

Section C: Definitions

touchscreen — A screen that is both an input device, because it senses your tap or swipe, and an output device, because it shows the picture.

Section D: Fill in the Blanks

tap or swipe = input

touchscreen shows picture = output

touchscreen = input AND output

button press = input
controller vibrates = output

microphone = input
speakers = output

Section E: Spot the Error

B — A touchscreen senses taps and swipes, so that is its input. The picture it shows is the output. Line 2 should be: input ← tap and swipe.

A — A keyboard is an input device only. The touchscreen is the device that is both input and output. Line 1 should be: IF device is touchscreen THEN.

A — A game controller that vibrates is also an output device, so it is both input and output. Line 1 should be: controller ← input and output.

D — The microphone is input and the speakers are output, so a headset is both. Line 4 should be: result ← input and output.

B — The touchscreen senses a tap, not a microphone. Line 2 should be: screen senses the tap.
