Gibson 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. Gibson's in-depth application coverage includes; the domain name system; the World Wide Web (both client- and server-side); Each chapter follows a consistent approach: Gibson 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.
