Computers in Control Systems

Abstract

In its relatively short existence, digital computer technology has touched, and had a profound effect upon, many areas of life. Its enormous success is due largely to the flexibility and reliability that computer systems offer to potential users. This, coupled with the ability to handle and manipulate vast amounts of data quickly, efficiently and repeatedly, has made computers extremely useful in many varied applications. The ability to communicate rapidly between remote networks has led to their extensive use in banking and commerce, because transactions can be conducted through links such as fibre optic cables or telephone channels. In fact the situation has advanced to the stage where the transactions can be initiated and completed without any human interaction.
