The course will present data communications fundamentals and
computer networking methods, using the ISO 7-layer reference model to
organize the study. Attention will be focused on the protocols of the
physical, data link control, network, and transport layers, for local
and wide area networks. Emphasis will be given to the Internet
Protocol Suite. Some advanced topics, such as network security and
multimedia networking, will also be covered.
Homework and programming assignments will help the students learn
how the Internet works and how to design and implement Internet applications.
Grade of C or better in STAT 344, CS 310 and CS 367.

Homework and project assignments are on a semi-regular basis. Both homework assignments and projects
are individual efforts. The official platform for projects is
site-unix, meaning that the TA will grade your projects on that
platform. Currently, site-unix points to zeus.ite.gmu.edu.
- If your code does not compile, you get no credit.
- Assignments and Projects are individual efforts.
- We reserve the right to use MOSS to detect plagiarism.
Your grade will be calcuated as follows:
- 20% Homework
- 25% Projects
- 25% Midterm exam
- 30% Final exam
No credit if your project does not compile. Late home assignments/projects lose 20% credit and will not be accepted
3 days after due, unless under prearranged conditions.
The final exam will be held on Dec. 16th, 4:30 - 7:15 PM. Tentatively,
the midterm exam will be held on Oct. 21st, 4:30 - 7:15 PM.
No early exams will be given.
Missed/make-up exams are strongly discouraged and must be arranged with the instructor BEFORE the exam
date with an official and verifiable excuse.
