Lectures and Notes

Lectures are held Tuesdays and Thursdays from 9-10:20am in CIT368. All lectures will be recorded and streamed live on Zoom.

Notes and readings will be posted shortly before each lecture. Recordings are viewable after the lecture via Panopto.

What are the different types of notes?

Each completed lecture has two types of notes:

  • “Blank” notes contain the unannotated notes and slides shown in class. During lecture, the instructor will annotate the slides and add more notes. We recommend using this version to take notes while following along with the lecture. Keep in mind these versions are inherently incomplete, because we will fill in examples during class!

  • “Class Notes” are the fully-annotated notes resulting from the lecture. These are the most complete sets of notes.

Legend for readings

Some of the readings listed here refer to sections of our various (not required) class textbooks, keyed by the name of the first author, specifically:

  • Dordal: “An Introduction to Computer Networks” by Peter Dordal. (Available free online).
  • Peterson: “Computer Networks: A Systems Approach” (5th edition), by Larry Peterson and Bruce Davie.
