What is Swapping ? Removing suspended or preempted processes from memory and their subsequent bringing back is called swapping. The basic idea of swapping is to treat main memory as a ‘pre-emptable’ resource. Lifting the program from the memory and placing it on the disk is called ‘Swapping out’. To bring the […]
