The 2022-23 version of this lesson started with a prompt discussing a Library situation of moving books either in the fastest way possible or the most accountable way possible. This warm question has been changed in the new 2023-24 course, yet the slide at the end of the lesson contrasting UDP/TCP still uses the wording of the Library example. Also the lesson plan has not been modified to match the new lecture slides.
This lesson really needs some work done to it and I would suggest a proper table contrasting UDP/TCP instead of using the terms only in the context of the Library example that is now gone.
