This book examines a wide range of techniques, technologies and systems used in data communications and computer networks. In particular it addresses a variety of data transmission methods used to convey data between physically distant locations. A number of types of network are considered which may interconnect a few or many thousands of users on either a permanent or temporary, switched basis. In order to support successful communication, a set of rules and procedures has been developed, many of which are embodied in internationally agreed standards. We shall look at the standard bodies and their standards and recommendations and also how they are used in practice.

The organized material that resulted in this book is an attempt to provide a reasonable degree of balance between rigor, clarity of presentation and at the same time keeping the length of book at manageable level. The principal objective of the book is to provide an introduction to various computer network fundamentals and to develop a foundation that can be used as basis for research and further study in this field.

Readers of this book:
The book has been written to position itself within the marketplace midway between a number of excellent texts in this subject area which may be regarded as comprehensive, and almost reference works, and a number of other texts which are rather brief and tend to be merely primers. Reference texts can be too detailed and large for a newcomer to the topic and the primer type of text can lack information and be rather bland for many readers. With this in mind the book is written to appeal to two broad ranges of readers:

1. Students of computer science/electronics engineering undergraduate and postgraduate courses who are studying data communications and/or computer networks.
2. Professional engineers, managers and users who work with computer networks in their everyday work. Here the book may be used either as an introductory text for personnel moving into the field or for updating in cases where previous experience has predominantly been in the area of traditional telecommunications.
