Define paging , Operating System

Paging: Only the needed memory pages are moved to main memory from the swap machine for execution. Process size does not matter. Produce the concept of the virtual memory. It gives greater flexibility in mapping the virtual address space into the physical memory of the system. Accept more number of processes to fit in the main memory. Accept the greater process size than the available physical memory. Demand paging systems operate the memory more flexibly.
