Networking 101 is:

A Free Textbook for a college-level Intro to Networking course

What are the first things you need to know about networking? Answering that question is our goal.

It is a college-level introduction to data communications and networking. It covers the information appropriate to an introductory one-semester (forty class hour) course in networking.

We focus on target skills, concepts, and topics that are normally expected of students who have passed such a course. We also cover the basic skills and concepts that support these target objectives.

Revisions are ongoing. New sections will appear and existing sections will be revised. Suggestions are welcome: email doncolton2@gmail.com

The book is typeset using LaTeX. The author is Don Colton, Associate Dean in the College of Business, Computing, and Government at Brigham Young University Hawaii.
