Preface of Computer Networks and Internets 5th Edition book:
Previous editions of Computer Networks And Internets have received incredibly positive reviews; I especially thank readers who have taken the time to write to me personally. In addition to students who use the text in courses, networking professionals have written to praise its clarity and describe how it helped them pass professional certification exams. Many enthusiastic comments have also arrived about foreign translations. The success is especially satisfying in a market glutted with networking books. This book stands out because of its breadth of coverage, logical organization, explanation of concepts, focus on the Internet, and appeal to both professors and students. 

In response to suggestions from readers and recent changes in networking, the new edition has been completely reorganized, revised, and updated. Descriptions of older technologies has been reduced or eliminated. Material on data communications, which is becoming an essential staple of networking courses, has been expanded and placed in Part II of the text. The networking chapters build on the data communication basics, and describe both wired and wireless networking. In addition, to emphasize the new 802.11 wireless standards, the discussion of wireless includes cellular telephone technologies because cellular systems currently offer data services and will soon be adopting Internet protocols.

Recent discussions about networking courses have engendered a debate about the bottom-up or top-down approach. In bottom-up, a student learns the lowest-level details, and then learns how the next higher levels use the lower-levels to provide expanded functionality. In top-down, one starts with a high-level application and only learns enough of the next lower layer to understand how the application can operate. This text combines the best of each. The text begins with a discussion of network applications and the communication paradigms that the Internet offers. It allows students to understand the facilities the Internet provides to applications before studying the underlying technologies that implement the facilities. Following the discussion of applications, the text presents networking in a logical manner so a reader understands how each new technology builds on lower layer technologies. 

The text is intended for upper-division undergraduates or beginning graduate students, who have little or no background in networking. It does not use sophisticated mathematics, nor does it assume a knowledge of operating systems. Instead, the text defines concepts clearly, uses examples and figures to illustrate how the technology operates, and states results of analysis without providing mathematical proofs. The text answers the basic question “how do computer networks and internets operate?” in the broadest sense. It provides a comprehensive, self-contained tour through all of networking that describes low-level details such as data transmission and wiring, network technologies such as LANs and WANs, internetworking protocols, and applications. It shows how protocols use the underlying hardware and how applications use the protocol stack to provide functionality for users. 

The text is divided into five parts. The first part focuses on uses of the Internet and network applications. It describes protocol layering, the client-server model of interaction, the socket API, and gives examples of application-layer protocols used in the Internet.
