Detailed explanation-1: -Virtual memory uses both hardware and software to enable a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM) to disk storage. Mapping chunks of memory to disk files enables a computer to treat secondary memory as though it were main memory.
Detailed explanation-2: -Virtual memory allows to use more memory than is physically available on the computer. Virtual memory is a common part of most operating systems found in desktop computers.
Detailed explanation-3: -If virtual memory doesn’t exist, we can’t load more than one program in the main memory. This means that without virtual memory, we can only run one program at a time. This is because each program might have to use different functions that may point to the same addresses in RAM.
