This page provides links to course content including lectures, in-class laboratories, at-home exercises, design projects, and exams used in the class during the Spring 2003 offering. The number associated with each item corresponds to the week of the class. For example, "Lecture 4" was given in the fourth week of the semester. There are no items from Week 8 due to cancellation of classes because of snow.

The items here are mostly PDF files. Original Microsoft PowerPoint and Word documents are available, upon request, for non-commercial, academic class use by instructors. Instructors should send requests to networking@vt.edu.
