In the context of section , the standard swapping procedure typically follows a strict algorithm to ensure system stability:
When the scheduler decides that a swapped-out process is ready to resume execution, the OS locates its memory image on the backing store. It then allocates a new block of free memory in RAM and copies the process back from the disk. Once loaded, the process is moved from the "suspended" state to the "ready" state.
Mobile operating systems use a variation called – compressed swapping in RAM. Before swapping a process to disk, they compress it in a reserved area of memory. This is a direct evolution of 9.5.6 principles, acknowledging that flash storage has limited write cycles.
