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.
