CS158a Spring 2023 Lecture Notes

Computer Networks

Videos of lectures are available.

Below are my lecture notes for the class so far. They should serve as a rough guide to what was covered on any given day. Frequently, however, I say more in class than is in these notes. Also, I tend to dynamically correct typos on the board that might appear in these lecture notes. So caveat emptor.
