《计算机网络》(第4版)是国内外使用最为广泛的计算机网络经典教材。全书按照网络协议模型（物理层、数据链路层、介质访问控制子层、网络层、传输层和应用层），自下而上系统地介绍了计算机网络的基本原理，并给出了大量实例。在讲述各网络层的同时，还融合进了近年来迅速发展起来的各种网络技术，如Internet、SONET、ADSL、CDMA、WLAN和蓝牙等。另外，针对当前计算机网络的发展现状以及计算机安全的重要性，《计算机网络》(第4版)用了一整间的篇幅对计算机安全进行了深入讨论。

Appropriate for courses titled Computer Networking or Introduction to Networking at both the undergraduate and graduate level in Computer Science, Electrical Engineering, CIS, MIS, and Business Departments. In this highly anticipated revision, Tanenbaum takes a structured approach to explaining how networks work from the inside out. He starts with an explanation of the physical layer of networking, computer hardware and transmission systems; then works his way up to network applications. Tanenbaum's in-depth application coverage includes email; the domain name system; the World Wide Web (both client- and server-side); and multimedia (including voice over IP, Internet radio video on demand, video conferencing, and streaming media. Each chapter follows a consistent approach: Tanenbaum presents key principles, then illustrates them utilizing real-world example networks that run through the entire book-the Internet, and wireless networks, including Wireless LANs, broadband wireless and Bluetooth. This new Fourth Edition contains a new chapter devoted exclusively to network security.The textbook is supplemented by a Solutions Manual, as well as a Website containing PowerPoint slides, art in various forms, and other tools for instruction, including a protocol simulator whereby students can develop and test their own network protocols.
