The text for the course is Andrew S. Tanenbaum, ``Computer Networks 4th Ed.'', Prentice Hall, 2003, ISBN 0-13-066102-3. There will be readings assigned for each lecture. You should do the readings before attending the lecture.

There is a discussion group for the course where you can post and discuss questions that arise from the course material. To get access to the group, send email to the course account and an invite will be sent to you for the group.

If you find additional websites that you think may be helpful for the course, let me know and I will add them here.

Marking Scheme

A course mark will be assigned based on three assignments, a written midterm, and a written final examination. Each student has the choice of one of the two marking schemes; the marking scheme most beneficial to each student will be used.

Marking Scheme II 30% 0% 70%

Midterm and Final Exams

For both exams Photo Identification is required. No paper or electronic electronic aids, such as dictionaries, calculators or talking slide rulers, are allowed.

Penalties for Academic Misconduct

Students caught cheating on an assignment or an exam will be assigned a mark of 0 for that assignment or exam. Furthermore, the case will be forwarded to the department chair for further prosecution resulting in a possible suspension or expulsion from the university.

Do not cheat or plagiarize!

To avoid the possibility of plagiarism here are some rules of thumb that you should follow:

  1. Put away pens, pencils, and keyboards when discussing the problem with others.
  2. Acknowledge all help that you received on the assignment in an acknowledgments section at the end of your write-up.
  3. Look at other code all you want, but do not copy it.
  4. If you are unsure about something ask the instructor!
