  • Grading currently will be based on two exams, 6-10 quizzes and 1-2 assignments. Specifically, quizzes will be announced at least one class period in advance. There will be one midterm exams and a final. The material covered in the exams will be drawn from the lectures and the quizzes. There will be several assignments which will be done in groups. The goal of the assignments is to provide you with hands-on experience with handling various kinds of computer networking topics. In the lectures, you will be introduced to computer networks and their different types and techniques used to transmit and receive data around their nodes. Specific details and due dates will be announced in class.

  • Slides, assignments, and other useful information will be posted on the course web page. Regular attendance is highly recommended. If you miss a class, you are responsible for all material covered or assigned in class. The neworking assignments are to be completed in groups; however, all members of a team are expected to fully understand the structure of the assignment. Discussion of the networking assignments is allowed and encouraged. However, each team is expected to do his/her own work. Assignments which are too similar will receive a zero. No late submission assignments will be accepted unless there is an extreme emergency.
