About this course

This course is intended as an introduction to both computer networking and operating systems for computer scientists. Students will get a comprehensive overview of the key protocols and the general architecture of the Internet, as one example of more general principles in network design, and acquire hands-on experience in programming different aspects of a computer network. In addition, the course provides a full introduction to modern operating system design, including memory management, scheduling, I/O, protection, and so on. The architecture of Unix-like operating systems (such as Linux) is used as an example of more general principles in OS design.

Note: The assignments must be handed in using Git (if you want to receive feedback). Create a new folder for each assignment. This tutorial explains how the hand-in procedure works in detail.

Sometimes, some of the TAs use slides in the recitation sessions. Ercan puts his slides here.
