helps maintain and improve the performance of a computer system

software used by humans to complete a task

Software and embedded systems

Operating system

The processor

The fetch-execute (FE) cycle

Main memory

Secondary storage

Computer specifications

Environmental impacts of computing devices

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.
