Description

In this unit pupils will discover the difference between general purpose and embedded systems. They will examine computer architecture and the components that make up a processor. Pupils will recognise the need for storage and be able to select a suitable storage device for a given purpose.

As pupils progress through the GCSE, it is important they understand what happens inside the computer systems they rely on every day. This unit gives them the knowledge to see beyond the screen, showing how simple logical operations form the foundation of all computing processes. By understanding how data is stored and managed, pupils can make informed decisions about storage solutions and appreciate the trade-offs between different technologies. Exploring the environmental impact of computing encourages pupils to think critically about how digital systems affect the world.
