Abstract
The purpose of a computer system is to produce output. This output may be in the form of a printed document, it may be in the form of a screen display or it may even be in the form of the state of the computer’s memory. Whatever form the output may take it is dependent upon, among other things, input. If we are to describe the behaviour of the computer in analytical terms then one of the factors we need to be able to describe is how an output is obtained from an input.
