Representing and manipulating data in computers
Computers are designed to receive, store, manipulate and present data. This unit explains how computers do this, with reference to the examples of a PC, kitchen scales and a digital camera. In particular it explores the idea that the data in a computer represents something in the real world.
This unit is from our archive and is an adapted extract from Computers and processors (T224) which is no longer taught by The Open University. If you want to study formally with us, you may wish to explore other courses we offer in.
