Virtual memory refers to a file or partition on a hard disk that is used to complement the Random Access Memory (RAM) in a PC. Since the capacity of hard disks is generally much more than the RAM that can be installed, virtual memory allows an operating system to run more applications simultaneously than would be possible using RAM alone.
