ABOUT THE BOOK The Computer Networks book helps you to understand the basic concepts of a computer network and how data communicaon is performed by using a computer network. The book concentrates on the OSI reference model, including the major issues and related protocols studies in the various layers of the OSI model, such as physical, data link, network, transport, session, presentaon, and applicaon. Moreover, the book provides a fundamental knowledge of the various aspects of computer networking and is designed from the engineering perspecve.
