Question

State and Explain swapping.

Answer 1

Swapping means changing or jumping

Answer 2

$\huge\bold\red{SWAPPING:-}$

• Swapping is a mechanism in which a process can be swapped/moved temporarily out of main memory to a backing store , and then brought back into memory for continued execution.

• For example, assume a multiprogramming environment with a round-robin CPU-scheduling algorithm. When a quantum expires, the memory manager will start to swap out (move) the process that just finished, and to swap in(bring back) another process to the memory space that has been freed.

• A process must be loaded into memory in order to execute.

• If there is not enough memory available to keep all running processes in memory at the same time, then some processes who are not currently using the CPU may have their memory swapped out to a fast local disk called the backing store.
