Answer Key

Describing a digital system and its network

Section A: Quick Questions

A — It names the hardware, the software and the network link

B — The software and the network link

B — A line from the device to the router

A — The router sends data packets between the tablet and the internet

A — Operating system

Section B: Match the Pairs

Hardware: CPU, RAM, storage, screen → Names the physical components that make up the digital system

Software: operating system, apps → Names the programs that tell the hardware what to do

Showing the network link in a diagram of a system → Laptop <--Wi-Fi--> Router <--> Internet

Explaining a part's function in a description → CPU: processes instructions for the system

Laptop: CPU, RAM, storage, screen, apps → No network link is shown, so the description is incomplete because it never says how the laptop connects to a network

Parts: CPU, RAM, storage, network adapter → Only the part names are listed, with no software and no explanation of what each part does

Section C: Definitions

system description — A full description of a digital system: it names the hardware components and software, shows the link to a network, and explains what each part does.

Section D: Fill in the Blanks

System: School laptop
Hardware: CPU, RAM, storage
Software: operating system

Hardware: CPU, RAM, storage
Software: operating system, web browser

Network: laptop connects by Wi-Fi
to the router at school

CPU - processes data and runs instructions

Laptop -> Wi-Fi -> Router -> Internet

Section E: Spot the Error

A — The system name is text, so it needs quotes. It should be system = "Tablet".

B — Chrome is software, not a hardware component. The hardware list should only hold physical parts such as "CPU" and "SSD".

B — The hardware list is missing its closing bracket. It should end with ].

C — RAM is a hardware component, not software. The software list should hold programs such as "macOS" and "Word".

D — A mouse is a peripheral, not a network device. The network link should go to a network device, so it should be "Cable to router".
