内容简介：
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.
