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.

What is a general purpose computer system designed to do?

Which of the following is an example of application software?

Perform the task (e.g. write a document).

Arrange these steps to use application software on a general purpose computer:

Which utility software helps organise files on a hard drive to improve performance?
