基本説明
Designed for a one-semester undergraduate course in Business Data Communications for Information Systems students, this book focuses on providing working knowledge of the data communications concepts and technologies that most students are likely to encounter after graduation instead of trying to cover every possible topic and technology in this vast field.

Numerous lab exercises are integrated throughout the pages to demonstrate how the material is applied.
