About the Product

Data communications and computer networks are vital in today's business world. DATABASE COMMUNICATIONS AND COMPUTER NETWORKS, 7th Edition balances technical and practical everyday aspects of data communications for future business managers, computer programmers, and system designers needing a thorough understanding of basic features, operations, and limitations of different types of computer networks. The Seventh Edition retains many of the elements that made past editions so popular, including readability and coverage of the most current technologies. This book offers full coverage of wireless technologies, industry convergence, compression techniques, network security, LAN technologies, VoIP, and error detection and correction.


  • Thirteen chapters introduce computer networks and data communications and include coverage of the language of computer networks and the effects of data communications on today's society.

  • "Details" sections separate highly technical material from the rest of the chapter narrative.

  • "In Action" examples demonstrate the chapters' key topics in a realistic work environment.

  • "Thinking Outside the Box" exercises at the end of each chapter challenge users to explore ideas beyond those explicitly outlined in the chapter.
