      Virtual Memory is used to augment physical memory (RAM). Specifically, when you run out of RAM, virtual memory is used (in the form of a swap file on your hard disk) to temporarily store the oldest least used used information until it is needed at which point it is swapped back into physical memory. Without this concept, you would more than likely run out of memory in many cases and your computer would simply crash.
