Market: For undergraduate courses in Computer Science & Information Technology, Electronics & Communications Engineering/MCA With the advent of the World Wide Web, the Internet has rapidly become the dominant type of computer network. It now enables people around the world to use the Web for E-Commerce and interactive entertainment applications, in addition to e-mail and IP telephony. The fifth edition of this highly successful text has been completely revised and restructured to focus entirely on the Internet and so avoids the necessity of describing protocols and architectures that are no longer relevant. As many Internet applications now involve multiple data types--text, images, speech, audio and video--the book explains in detail how they are represented. This is made accessible by extensive use of illustrations and worked examples that make complex systems more understandable. This makes the book ideal for self-study or classroom use for students in computer science or engineering, as well as being a comprehensive reference for practitioners who require a definitive guide to networking.
