Computer Science

a computer designed to perform many different tasks

a small computer built into a device to control specific functions

helps maintain and improve the performance of a computer system

software used by humans to complete a task

Software and embedded systems

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.
