Several methods that has increased effectiveness of memory management like the Virtual memory systems which separates the memory addresses used by a process from actual physical addresses, thus allowing the separation of processes and increasing the size of the virtual address space beyond the available amount of Random Access Memory (RAM) using paging or swapping to secondary storage have been used.
