My internet connection was physically severed, so this was streamed over a cell phone connection off a laptop, so some of the supplementary diagrams didn't show up in the recording. It only recorded the PowerPoint slides.

The general topic of today was how a Memory Management Unit works, and how it presents to the programmer the illusion of having all of RAM to itself, but in reality it maps different pages of memory to different parts of physical RAM, and ensures that you don't go outside the boundaries of your segments. Pages of memory can also get written to disk (invisibly, without you knowing it) and then when accessed trigger a page fault, which will bring them back in.
