An introduction to computer networking grounded in real-world examples

In Computer Networks, Tanenbaum et al. explain how networks work from the inside out. They start with the physical layer of networking, computer hardware and transmission systems, then work their way up to network applications. Each chapter follows a consistent approach: The book 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. The 6th Edition is updated throughout to reflect the most current technologies, and the chapter on network security is rewritten to focus on modern security principles and actions.

Tutorial videos on key networking topics and techniques are available to students on the companion website.

Instructors are supported with a Solutions Manual to end-of-chapter exercises featured in the book, Lecture PowerPoint slides, and extracted art and figures featured in the book.
