Computer Science

measured in gigahertz, this defines thenumber of FE cycles the CPU can complete per second

onboard memory of the CPU, measured in megabytes

mini processor inside the CPU carrying out instructions independently

Computer specifications

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.

Computer Systems
