As one of the fastest growing technologies in our culture today, data communications and networking presents
a unique challenge for instructors. As both the number and types of students are increasing, it is essential to
have a textbook that provides coverage of the latest advances, while presenting the material in a way that is accessible
to students with little or no background in the field. Using a bottom-up approach, Data Communications and Networking
presents this highly technical subject matter without relying on complex formulas by using a strong pedagogical
approach supported by more than 700 figures.
Now in its Fourth Edition, this textbook brings the beginning student right the forefront of the latest advances
in the field, while presenting the fundamentals in a clear, straightforward manner. Students will find better coverage,
improved figures and better explanations on cutting-edge material. The "bottom-up" approach allows instructors
to cover the material in one course, rather than having separate courses on data communications and networking.
New Features
Visual approach is supported with hundreds of figures and animations on the text website
Strong in-text pedagogy is designed for the beginning student and includes numerous figures, highlighted points,
examples and real life applications, key terms, chapter summaries, practice sets and an extensive glossary and
list of acronyms.
Text uses a bottom-up approach where students learn about data communications before learning about networking.
This approach allows instructors to cover the material in one course, rather than having separate courses on data
communications and networking.
