Understanding Data Communications and NetworksThe explosion of the World Wide Web has created greater awareness of computer networks, and has made understanding network fundamentals and data communications essential. The Second Edition of Shay's best-selling book combines a solid and well-respected presentation of data communications and network fundamentals, with important information on the state-of-the-art developments that support the World Wide Web. New topics include asynchronous transfer mode (ATM), modems, and new topics in encryption and network security. Expanded coverage of LAN/WAN systems and protocols includes the Netware LAN operating system and TCP/IP and IPv4 WAN protocols, with new coverage of the IPv6 WAN protocol. Dr. Shay presents these fundamentals, and a wide array of specific applications, at exactly the right level for Junior CS and CIS majors intending to be information systems professionals. |
