controlling operations that are expressible in numerical or logical terms. Computers are constructed from components that perform simple well-define functions. The complex interactions of these components endow computers with the ability to process information. If correctly configured (usually by programming) a computer can be made to represent some aspect of a problem or part of a system. If a computer configured in this way is given appropriate input data, then it can automatically solve the problem
