Topic 1 Computational Thinking
Breaking a problem down into smaller, manageable parts.
What is decomposition?
The base-2 number system used by computers.
What is binary?
The component of the CPU that manages and coordinates instructions.
What is the Control Unit?
A collection of devices connected together to share resources.
What is a network?
Malicious software designed to damage, disrupt or gain unauthorised access to a computer system.
What is malware?
Removing unnecessary detail so you can focus on what really matters.
What is abstraction?
The denary value of the binary number 10110101.
What is 181?
Temporary memory that stores instructions and data currently in use.
What is RAM?
A device that forwards data packets between different networks
What is a router?
An attack that overwhelms a system with traffic so legitimate users cannot access it.
What is a denial‑of‑service (DoS) attack?
A logical diagram using standard symbols to represent the steps in an algorithm.
What is a flowchart?
An image representation made up of a grid of pixels, each with stored colour values.
What is a bitmap (raster) image?
The bus that is bi‑directional and transfers actual instructions and data.
What is the data bus?
A set of rules governing how data is transmitted over a network.
What is a protocol?
A concern where decisions made by AI systems may reflect bias present in the data they were trained on.
What is algorithmic bias?
This set of steps shows a precise, language‑independent way of describing a solution.
What is pseudocode?
The hexadecimal value of the binary number 11001110.
What is CE?
Why the address bus is one‑way only and never bi‑directional.
What is because addresses are only sent from the CPU to memory and not returned?
The protocol used to retrieve emails from a mail server while leaving copies on the server.
What is IMAP?
The UK law that protects original creative work such as software, music and images from unauthorised copying.
What is the Copyright, Designs and Patents Act?
A rectangle with a smaller rectangle inside
What is the flowchart shape for a sub program
The hexadecimal number that represents the binary value with all bits set in a single byte.
What is FF?
The register that stores the address of the next instruction to be fetched from memory.
What is the Program Counter (PC)?
The TCP/IP layer responsible for routing packets between networks using IP addresses.
What is the Internet layer?
The amount of e-waste in tonnes produced by the UK just in 2024. (A double decker bus is 14 tonnes)
1.6 Million Tonnes
