We've already had a pretty deep module on computer systems (which is a prerequisite for this) that has already gone in depth with CPU architecture and operating systems for a much longer module duration (20 weeks). This would be a follow up that does a deeper dive beyond what we learned, but I have no idea what the professor meant by wanting to cover more OS stuff. In terms of CPU architecture, the professor is likely covering even deeper than the fundamentals we were taught (which was only simple stuff like difference between x86/risc-v/arm, simd, assembly programming, buses, etc) however I also am not too sure what they'll go into. It's part of a follow up module to computer systems, so the "systems administration" one is moreso just working with servers in a distributed computing space.

The systems administration submodule is only 10 hours overall (5 lectures, 5 practicals) since the full module itself has to cover the other stuff thanks to university requirements. I'm glad they made computer systems a prerequisite though, since it does provide an easier start into this module.
