Computer Networks: Fourth Edition — Problem Solutions

Networking concepts become easier to revisit when the reasoning behind a problem is laid out clearly. This companion to the fourth edition of Computer Networks collects Andrew S. Tanenbaum’s solutions to chapter problems, with coverage ranging from network architecture and protocols to transmission, switching, and communication theory.

Follow the reasoning behind the answers

The solutions work through questions involving topics such as network topologies, layered models, TCP and UDP, bandwidth and latency, signal transmission, and packet switching. Alongside conceptual explanations, the material includes numerical calculations—useful when a problem calls for more than remembering a definition.

A chapter-organized study companion

Arranged by chapter, the volume follows the structure of the fourth-edition textbook. It can help readers check their approach to selected exercises, trace a calculation, or review how networking principles connect across a problem set. The covered material includes problems from Chapters 1 through 8.

For readers using the fourth edition

This is a solutions companion, not the main textbook or a standalone introduction to networking. It is most relevant to students and instructors working with Tanenbaum’s fourth edition, especially when revisiting its exercises and the networking concepts they test.
