Virtual Memory is basically that the operating system presents the application with a flat address space, any of which can be accessed at any time and any amount can be used, regardless of how much physical memory is present. If the demand for physical memory gets too great, the system discards data not used recently, writing it to disk if necessary. If that data is then accessed, the system automatically reloads it somewhere in physical memory, then updates the virtual memory map to point to that physical memory.

Overlays are sections of program that can be loaded in, under program control, while the program is running, replacing other parts of the program. Many DOS apps made use of overlays to cram programs bigger than available memory (I recall Microsoft Works used overlays). Swapping is where the operating system shuffles pieces of program around in memory, loading from disk and discarding as necessary, without notifying the program that this is happening.

Segmentation and paging are two different sorts of swapping. Segmentation works on programmer-declared variable-size portions of a program called segments. Paging works on fixed size portions of programs or data called pages. The difference is that it's easier for the OS to locate blocks of memory if they're all the same size, making paging more predictable, but at the cost of the program incurring multiple swap operations to bring in a given piece of functionality (each different page hit causes the processor to raise a page fault exception, which causes the OS to locate that data, whereas if segmentation is used, the whole segment could be brought in).

Stability. What an interesting concept. -- Chris Maunder
