  Suitable for those with little or no background, this text offers an overview of networking and Internet technology. It provides a tour through all of networking, from the lowest level of data transmission and wiring to the highest levels of application software. An accompanying CD-ROM and Web site provide opportunities for a variety of hands on experiences. The CD contains copies of text figures, digitized images of network wiring and equipment, and files of data that can be used as input to student programs, a key search mechanism, and links to the Web site.

  Computer Networks and Internets is appropriate for all introductory-to-intermediate courses in computer networking, the Internet, or Internet applications; readers need no background in networking, operating systems, or advanced mathematics. Leading networking authority Douglas Comer presents a wide-ranging, self-contained tour of the concepts, principles, and technologies that enable today's Internet to support applications ranging from web browsing to telephony and multimedia. This Fifth Edition has been thoroughly reorganized, revised, and updated: it includes extensive new coverage of topics ranging from wireless protocols to network performance, while reducing or eliminating coverage of older protocols and technologies. Comer begins by illuminating the applications and facilities offered by today's Internet. Next, he systematically introduces the underlying network technologies and protocols that make them possible: low-level data communications; packet switching, LAN, and WAN technologies; and Internet protocols such as TCP, IP, UDP, and IPv6. With these concepts and technologies established, he introduces several of the most important contemporary issues faced by network implementers and managers, including quality of service, Internet telephony, multimedia, network security, and network management. Comer has carefully designed this book to support both top-down and bottom-up teaching approaches. Students need no background in operating systems, and no sophisticated math: Comer relies throughout on figures, drawings, examples, and analogies, not mathematical proofs.

  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.
