description: Slides from a lecture on various networking topics, including how TCP actually works

In the same vein as my [previous post](/2016/04/25/stack-smashing.html), I'd
like to share another lecture I wrote for the honors section of the
[systems programming course](https://cs.illinois.edu/courses/profile/CS241)
I am a TA for. It is essentially a taste of some deeper networking concepts
than we get to cover in the regular section. This includes a fairly substantial
discussion of how TCP works beneath the scenes, a topic I continue to be
fascinated by.

One of the benefits of writing a lecture is that it forces you to work through
your own conceptual understanding of a topic and patch holes that you won't
necessarily realize exist in the first place. I can definitely say this applied
here. I especially enjoy when students ask clarifying questions about some of
the finer details (for this lecture, I had one about specifics of reliable
transmission) as we can see what limitations the material has and where it can
be improved.
