I’m surprised you had that many. My CS program had nothing comparable that I can remember.
Definitely not computer science.
Definitely not computer science.
We had another called "Operating Systems" that focused on things like concurrency, building a really basic memory pager, etc (mix of C and Java I think)
And we had one other called "Networking" that was sort of along the same lines as "Operating Systems" but focused on, well, networking. Mostly Java; we wrote our own application-layer protocols, that sort of thing
But yeah pretty much everything else - including the more "concrete" programming courses like Data Structures and Algorithms - was fairly abstracted away from any specific system
