Inside the PC
This large board connects the CPU, RAM, storage and other computer components.
Motherboard
Known as the “brain” of the computer, this component runs instructions and controls other components.
CPU
CDs, DVDs and Blu-ray discs belong to this storage category.
What is optical storage?
This is the worldwide network that connects computer devices.
What is the internet?
This security method changes readable data into a secret code.
What is encryption?
This component stores files and programs even after the computer is turned off.
What is a storage drive?
This component renders graphics, textures and visual effects in games.
GPU
This storage technology uses magnetised areas on spinning disks to store data.
What is magnetic storage?
A wired network sends data through cables. A wireless network sends data using these.
What are radio waves?
This security measure checks network traffic and allows or blocks packets based on whether they appear safe.
What is a firewall?
This temporary memory stores the programs and files that a computer is currently using.
What is RAM?
A computer has a powerful CPU but a weak GPU. What problem might a gamer experience?

This software scans files, detects malware and can quarantine or remove harmful programs.
What is antivirus software?
A student wants to play a game, stream and use Discord at the same time. The number of what CPU specification will help it handle several tasks at once.
The number of CPU cores
Correct this statement: “A GPU has a few powerful cores designed for complex logic and decision-making.”
A CPU has fewer powerful cores for complex and sequential tasks. A GPU has many simpler cores designed for parallel tasks.
Give one advantage an SSD has over an HDD and one disadvantage.
An SSD is faster, quieter, more durable or uses less power, but it usually costs more per GB.
Large files travel across networks after being divided into these smaller pieces.
What are data packets?
This service creates an encrypted “tunnel” to a server and hides the user’s real IP address from websites.
What is a VPN?
