Answer Key

Digital system

Section A: Quick Questions

B — Hardware and software working together to input, process, store and output data

A — A tablet

A — Input

A — True, it has hardware and software that handle data for playing games

B — Every digital system is built to do a job, like communicating or playing games

Section B: Match the Pairs

digital system → A combination of hardware and software that inputs, processes, stores and outputs data for a purpose

smart speaker → A digital system that takes in voice input, processes it, and outputs sound or answers

A digital system is made of hardware and software working together to input, process, store and output data → laptop = hardware + software

Some digital systems contain other digital systems inside them → games console > controller

tablet = hardware only → A digital system needs both hardware and software. A tablet without software cannot input, process, store or output data for a purpose.

digital system = no purpose → Every digital system has a purpose, such as playing games, making calls or playing music. It is not just random parts.

Section C: Definitions

digital system — A combination of hardware and software that inputs, processes, stores and outputs data for a purpose, such as a laptop, tablet, smart speaker or games console.

Section D: Fill in the Blanks

digital system = hardware + software

A digital system inputs, processes, stores
and outputs data

A smart speaker inputs sound with a 
microphone

A digital system handles data for a purpose

A smart home is a system with other systems
 inside

Section E: Spot the Error

B — A speaker is an output device, not an input device. The laptop's input should be something like "keyboard", which sends data in.

B — A microphone is an input device that collects sound data. The CPU does the processing, so this line should be process = "CPU".

D — A hard drive stores data, so it is not an output device. The console's output should be something like "TV screen", which shows the results.

C — A battery is physical hardware, not software. The software list should hold programs such as "OS" and "apps".

B — RAM is a hardware component, not software. The software list should contain programs like "OS" and "apps".
