Introduction

It is difficult to define what "Information technology" is accurately. It is even more difficult to understand the plethora of terms used in connection with information technology, especially since so many new one are being coined. This Encyclopaedic Dictionary of Information Technology defines a large number of computer terms, both formal and informal, while, at the same time, giving lengthier descriptions of a number of terms of particular importance.

Objectives of the Dictionary

It has a number of emphases; first, to define all the important terms used in information technology; second, to define all terms used in as concise and meaningful a way as possible; third, in some cases where it is not possible to give a very full description, the references are given where more information can be obtained. Fourth, the book has been designed in such a way that each term can be easily accessible and understandable.

Design and Content

In order to make each definition self-contained, it is sometimes necessary to duplicate definitions but this has been reduced as far as possible. Finally, the terms are confined to those which are of current use and outdated terms have been omitted. Whenever necessary, line diagrams have been included to illustrate the terms fully.

Purpose of the Book

This book is intended to be a useful reference book which, it is hoped, will be of great use to students, lecturers, librarians, scientist, engineers, computer personnels and DPMs and to anyone with an interest in information technology.
