This classic best-seller has been completely revised and updated to reflect networking and internetworking technologies that will be most critical for years to come. Award-winning educator and researcher Andrew S. Tanenbaum explains how computer networks work inside--from the hardware technology up to and including the most popular Internet application protocols.

Throughout the book are running examples of ATM and the Internet. Tanenbaum's extensive coverage of the Internet, Asynchronous Transfer Mode (ATM) and wireless networking makes Computer Networks the first book to cover all three of these essential technologies, in addition to explaining the fundamental principles behind all computer networking.

Tanenbaum clearly presents:

• Internet applications such as the World Wide Web, Java, email, Usenet, multimedia, the Mbone, and the Domain Name System
• Network security, including secret- and public- key algorithms, authentication protocols, and digital signatures.
• TCP/IP and the latest internetworking technologies such as Mobile IP and IPv6 which are built atop the Internet's protocols
• ATM: How it works in wide area (B-ISDN) and LAN environments
• Local area networks, including IEEE, 802, FDDI, HIPPI, and Fibre Channel
• The major wireless and mobile technologies, including such as AMPS, GSM, CDMA, and CDPD
• Detailed discussions of the principles, modeling, and performance of protocols in various layers
• Discussions of the underlying hardware technologies, from fiber optics to wireless communication

With 250 exercises, a separate solutions manual, protocol simulation software files written in C and figure files available for downloading, the book is perfect for students and networking professionals.
