To free user programs from the need to carry out storage allocation and to permit efficient sharing of the available memory space among different users. By moving unused files to the hard disk, a computer frees up space in its RAM to perform current tasks . All memory references within a process are logical addresses that are dynamically translated into physical addresses at run time. But with time, when there is a need for other pages, then the CPU will find that page from the secondary memory and load that page in the main memory. a) oldest page is chosen Virtual memory is a memory management technique that can be implemented using both hardware and software.

Virtual memory is a valuable concept in computer architecture that allows you to run large, sophisticated programs on a computer even if it has a relatively small amount of RAM. 1 Because of virtual memory the memory can be shared among a processes b threads. So, the benefit of using the Virtual Memory is that if we are having some program that is larger than the size of the main memory then instead of loading all the pages we load some important pages.
