Comp 343-001/443-001, Computer Networks, Fall 2018

Peter Dordal, Loyola University Chicago Dept of Computer Science.

The class meets Tuesdays, 4:15-6:45, in Corboy 208.

The text will be An Introduction to Computer Networks, written by myself and available for free online. The book is updated at regular intervals; if you download for offline reading, you may want to re-download as necessary.

My general course groundrules are here. Exams will count for between 70% to 80% of your grade, with homework and programs making up the rest.

The midterm will be October 23 and the final will be December 11. The final will be at our usual time, and in our usual room.
