  For one-semester, undergraduate/graduate introductory computer networking courses in Computer Science, Electrical Engineering, CIS, MIS, and Business Departments. Written by a best-selling author and leading computer networking authority, this text builds a comprehensive picture of the technologies behind Internet applications. Ideal for those with little or no background in the subject, the book answers the basic question how do computer networks and Internets operate? in the broadest sense and includes an early optional introduction to network programming and applications. The text provides a comprehensive, self-contained tour through all of networking from the lowest levels of data transmission and wiring to the highest levels of application software, explaining how underlying technologies provide services and how Internet applications use those services. At each level, it shows how the facilities and services provided by lower levels are used and extended in the next level. For instructors who want to emphasize Internet technologies and applications, the book provides substantial sections on Internetworking and Network Applications that can serve as a focus for a course.An accompanying multimedia CD-ROM and Website provide opportunities for a variety of hands-on experiences.

  If you really want to understand how the Internet and other computer networks operate, start with Computer Networks and Internets, Third Edition. Douglas E. Comer, who helped build the Internet, presents an up-to-the-minute tour of the Internet and internetworking, from low-level data transmission wiring all the way up to Web services and Internet application software. The new edition contains extensive coverage of network programming, plus authoritative introductions to many new Internet protocols and technologies, from CIDR addressing to Network Address Translation (NAT). Comer explains every networking layer, showing how facilities and services provided by one layer are used and extended in the next. Discover how networking hardware utilizes carrier signals, modulation and encoding; why internets use packet switching; how LANs, local loops, WANs, public and private networks work; and how protocols like TCP support internetworking. Understand the client/server model at the heart of most network applications, and master key Internet technologies such as CGI, DNS, E-mail, ADSL, and cable modems. This new edition includes a complete new chapter on static and automatic Internet routing, introducing key concepts such as Autonomous Systems and hop metrics; as well as detailed coverage of label switching and virtual circuits.
