This comprehensive introduction to networking has been thoroughly updated to reflect the latest technologies, particularly in wireless networking, including 802.11, Bluetooth, and broadband wireless. It also covers fixed networks such as ADSL, gigabit Ethernet, and peer-to-peer networks, alongside extensive new material on applications like Internet radio, voice over IP, and video on demand. The revised coverage of network security now occupies an entire chapter. Author Andrew S. Tanenbaum, a distinguished educator and researcher, meticulously explains how networks operate from the physical layer to the application layer. Key topics include the physical layer (copper, fiber, wireless, satellites), data link layer (protocol principles, HDLC, PPP), MAC sublayer (gigabit Ethernet, 802.11), network layer (routing algorithms, IPv4, IPv6), transport layer (socket programming, TCP, UDP), and application layer (e-mail, the Web, streaming audio). The book provides detailed descriptions of principles associated with each layer and includes numerous examples from the Internet and wireless networks, making it an essential resource for understanding both current and future networking technologies.
