Q3
A — Store
Q4
A — Output
Q5
B — Input
Section B: Match the Pairs
Q1
Phone touchscreen (tap) → Input: it sends your taps and swipes into the phone
Q2
Games console CPU → Process: it works on the game's data and decides what happens next
Q3
A part that keeps your saved games and photos even when the device is off has the job of store → Phone storage (saved photos)
Q4
A part with two jobs: a touchscreen shows pictures (output) and also senses your taps (input) → Touchscreen = output + input
Q5
Speaker = input → A speaker sends sound out to you, so it is output, not input.
Q6
Controller buttons = store → Controller buttons send your presses into the console, so they are input, not store.
Section C: Definitions
Q1
input, process, store, output — Each part of a digital system has one main job, so you can sort it as input (sends data in), process (works on it), store (keeps it) or output (shows results).Section D: Fill in the Blanks

Q1
B — A microphone sends sound data into the phone, so it is an input part. It should be: microphone = input.
Q2
B — A controller sends the player's button presses into the console, so it is an input part. It should be: controller = input.
Q3
C — A speaker plays sound for the user to hear. It shows results, so it is an output part, not a store part. It should be: speaker = output.
Q4
A — The touch part of a touchscreen sends your taps in as data, so its main job here is input. It does not work on the data. It should be: touchscreen = input.
Q5
D — A hard drive keeps games and saved files, so it is a store part. The CPU does the processing. It should be: hard drive = store.
