Chapter 5 and 6 were, again, classic CS stuff.
I can't help but feel that everything is scratching the surface but
I guess that it would be a great overview of a lot of things for CS
newcomers.

Chapter 5: The Process

We're presented with the process as the element of multi-tasking.

This page is missing: https://www.bottomupcs.com/context_switching.xhtml

Quote:UNIX systems assign each process a nice value. The scheduler looks at the
nice value and can give priority to those processes that have a higher
"niceness".

I think that's a typo and that they meant lower niceness.


Chapter 6: Virtual Memory

We get a good overview of what is virtual memory, why it's useful. The
definitions of page, offsets, frames, swapping, etc.. Along with hardware
related help like TLB, protection bits, and more.
