Summary
This book introduces computer networks by examining their functionality from underlying hardware to applications. It dissects and depicts the principles associated with each network layer, translating them through examples from the Internet and wireless networks. The book covers key networking technologies with emphasis on wireless networking (802.11, 802.16, Bluetooth, 3G cellular) and fixed-network coverage (ADSL, Internet over cable, gigabit Ethernet, MPLS, peer-to-peer networks).
Readers gain understanding of the physical layer (copper, fiber, wireless, satellites), data link layer (protocol principles, HDLC, PPP), MAC sublayer (gigabit Ethernet, 802.11), network layer (routing algorithms, congestion control, QoS, IPv4, IPv6), transport layer (socket programming, UDP, TCP), application layer (e-mail, the Web), and network security (AES, RSA). New coverage includes 3G mobile phone networks, Fiber to the Home, RFID, delay-tolerant networks, and 802.11 security, with expanded material on Internet routing, multicasting, congestion control, quality of service, real-time transport, and content distribution.

From the book
Computer Networks, Fifth Edition, is the ideal introduction to the networking field. This bestseller reflects the latest networking technologies with a special emphasis on wireless networking, including 802.11, 802.16, Bluetooth™, and 3G cellular, paired with fixed-network coverage of ADSL, Internet over cable, gigabit Ethernet, MLPS, and peer-to-peer networks. Notably, this latest edition incorporates new coverage on 3G mobile phone networks, Fiber to the Home, RIFD, delay-tolerant networks, and 802.11 security, in addition to expanded material on Internet routing, multicasting, congestion control, quality of service, real-time transport, and content distribution.
Authors Andrew Tanenbaum and Davis Wetherall describe the inner facets of the network, exploring its functionality from underlying hardware to applications, including:
