What is Virtual memory?

1.	What is Virtual memory?
Answer» Virtual Memory is a method of storage allocation where a part of secondary memory will be emulated as it is the main memory of a COMPUTER. The virtual memory will SOLVE the insufficient memory problem by converting part of disk memory into virtual addresses, thus will create a large size of RAM for accomodating the increased memory requirement demand and will provide the illusion that we have a lot of memory. MODERN MICROPROCESSORS will have a built-in Memory Management Unit(MMU) which will translate the virtual addresses into physical addresses. The size of virtual storage is limited by the computer SYSTEM’s addressing scheme and the available quantity of secondary memory will not depend on an actual number of the main storage locations. In common, Virtual memory will be implemented through demand paging or in a segmentation system. Also, demand segmentation can be used for providing virtual memory.
