In an expanded and completely updated edition "Understanding Data Communications" reflects the major changes to communications technology since 1990. The revisions will include: an update of the topical networks and information utilities chapter to include ATM and frame relay; the LAN chapter will include Ethernet and Token-Ring networks, the use of switching hubs to overcome bandwidth constraints, and ATM LAN versus WAN evolution. Other important changes include expanded coverage of satellite communications; a discussion of serial and parallel interfaces; and a fully updated chapter on the standards-making organizations illustrating what shapes the industry today. The book includes review questions and problems at the end of each chapter and covers the whole spectrum of data communications from first principles. It assumes little prior knowledge of networking.

Now in its third edition, Understanding Data Comunications, provides a comprehensive introduction to the field of data communications for both students and professionals. Assuming no prior knowledge of the field, it presents an overview of the role of communications, their importance, and the fundamental concepts of using the ISO′s 7–layer approach to present the various aspects of networking.
∗ Covers the evolving high speed network access via digital subscriber line, cable modems and wireless communication.
∗ Examines the role of regulatory and standardization bodies, the operation of the Internet and the use of a variety of electronic applications.
∗ Includes a series of comprehensive questions covering the important concepts from each section.
∗ Describes the digital network used by communications carriers and the methods used to obtain access to the digital highway.
∗ Discusses frequency division multiplexing which forms the foundation for the operation of several types of high speed digital subscriber line.
Aimed at the senior level undergraduate and graduate computer science student, it is also essential reading for data processing professionals and those involved in computer science and data communications.
"...designed to provide a solid foundation on how data communications systems operate, why, where, and when certain types of equipment should be networked together, and the role of evolving communications technology." (SciTech Book News, Vol. 25, No. 4, December 2001)
