ABSTRACT
This chapter explains some of the principles underlying the technology and looks at examples of the confluence of computers, microelectronics and telecommunications. The two words 'information technology', used together, have recently acquired special meaning. Governments have been saying that new information technology is the key to economic growth. They have also been saying that it is likely to bring about substantial changes in society. New information technology depends on three complex technologies that have recently converged: computing, microelectronics and telecommunications. In each of these technologies new materials, systems, tools and techniques are being invented at an astounding rate. The computer simply manipulated the information, that is, the words, in accordance with commands given as the text was typed or edited. Telecommunications provide the means to deliver information over distances great and small, accurately and speedily. Each year the pace of development accelerates, meaning that more information can be sent faster and more faithfully.
