Security Now episodes 233, 235, 237, 239 and 241 give a nice overview of the fundamentals of computing. In particular, they form an inter-linked collection of podcasts that go over computing starting at simple execution of a program utilizing a program counter through discussing indirection, stacks, recursion and, finally, interrupts. Each of the episodes builds upon the previous and covers many of the key points very lucidly. I would recommend them to people who want to get a quick overview of some of the elements of computing purely by listening to audio.
