computer help: What is virtual memory and how can I get some more? - Help.com

This is storage space on your hard drive supported by windows operating systems in conjunction with the computer memory RAM chip.

You can think of virtual memory as an alternate set of memory as your hard drive
doubles up its function as a RAM chip .

The purpose of virtual memory is to enlarge the address space, the set of addresses a program can utilize. For example, virtual memory might contain twice as many addresses as main memory. A program using all of virtual memory, therefore, would not be able to fit in main memory all at once. Nevertheless, the computer could execute such a program by copying into main memory those portions of the program needed at any given point during execution.
