Swap Space
Explore how swap space functions in operating systems to manage memory beyond physical limits. Understand the process of swapping pages between RAM and disk storage, how the OS tracks disk addresses, and the role of swap space size in supporting multiple processes. This lesson clarifies how swapping supports virtual memory to optimize system performance.

Assumptions
The first thing we will need to do is to reserve some space on the disk for moving pages back and forth. In operating systems, we generally refer to such space as swap space, because we swap pages out of memory to it and swap pages into memory from it. Thus, we will simply assume that the OS can read from and write to the swap space, in page-sized ...
