CS176A: Introduction to Computer Communication Networks
Basic concepts in networking, the OSI model, error detection codes, flow
control, routing, medium access control, and high-speed networks.
- Understand the challenges of network communication.
- Understand the basics of network communication.
- Understand the operation of the protocols that are used inside the Internet.
Course Objectives and Department Mission
Because the Internet is such an important part of the communications
infrastructure, understanding how it works is of benefit to everyone.
Understanding the Internet in detail is especially critical for Computer
Science students. Not only do students learn how communication takes place,
but the Internet serves as an excellent example of a highly distributed and
complex computer system. As a consequence, understanding the Internet fits
well with the CS Department's Mission.

- Moodle site requires "enrollment code", which is "cs176a"
- Course Material
- Two different styles of the class textbook:
- [Requred] J. Kurose and K. Ross, Computer Networking: A Top-Down Approach Featuring the Internet", Addison-Wesley, 2nd edition (July 2002), 3rd edition (May 2004), 4th edition (April 2007), or 5th edition (Mar 2009).
descriptive text, but top-down instead of bottom-up. Also, a bit light
on detail in some places, expect to have to occassionaly look elsewhere
for more detail.
- The fifth edition was just released. The third or fourth editions are
fine (and probably the second too).
- [Optional] Andrew S. Tanenbaum: Computer Networks, Prentice Hall, 4th Edition, August 2002.
- Terse but thorough. Some of the explanations can be quite confusing.
- Note: I used this book several years ago and while it still has some useful information, I tend to go by Kurose/Ross more.
- Shiv Kalyanaraman's Online Computer Networking Lessons
- A colleaque has put together some useful lessons. Try it, you might
- There is tons of additional information on the web about topics we will be covering.
Required Prerequisites: PSTAT120A or ECE139.
