IT 202, Internet and Applications
Final Exam 30%
Grades will be computed on a straight scale out of 100 possible points: 90-100=A, 87-89=B+, 80-86=B,
Lectures will be held from 1 – 2:25 pm in Kupfrian room 105. I tend to use PowerPoint slides for the main
points in my presentations, augmented with board-work when necessary. You can find a copy of the slides
that I’ll use on the course WebCT board at:
You’ll need your UCID and password to login. There is a tutorial on the login screen that you should use if
this is your first experience with WebCT.
Regular attendance in this course is mandatory. Role will be taken at the start of each class session.
Students with more than 3 unexcused absences will fail the course irregardless of your other grades. 2 late
arrivals count as an unexcused absence.
Homework will be assigned and collected weekly through WebCT through the ‘Assignments’ link on the
WebCT main page. Homework will be graded on a random basis. Your grade will be based on the score
that you receive on the homework I grade, however it is to your benefit to complete every assignment as
this will help you prepare for the midterm and final.
A network programming project will be required during the course. The project will be completed in teams
and involve creating a client/server application that uses the TCP/IP protocol suite to communicate. Details
of the project will be made available when we cover socket programming during the 4th week of class.
The midterm and final will constitute a significant portion of your overall grade. Exam times will be
announced as they become available. Both exams will be in a closed book/notes format and will contain
information from the text, as well as lectures. The final will be cumulative.
As a general rule, I do not give makeup exams without a legitimate reason (e.g., jury duty, serious medical
problem). If you have an emergency, I will make allowances as long as you provide proper documentation.
If for some reason you have a conflict that will cause you to miss an exam, please inform me immediately
so that we can arrange an alternate date for you to complete the test. You can send email or leave a phone
message on my answering machine at any hour of any day.
I do not give out extra-credit assignments.
If you must miss a class, lab, or exam because of a religious observance, it is your responsibility to report to
me within the first two weeks of classes which days you will be missing.
