virtual memory is that space on your hard disk that your computer can use is as if it was RAM.
this is very useful for computers that have very less actual RAM.
suppose you have 512mb of RAM and you set your virtual memory to 512 mb. them your total memory would be 512 + 512 = 1024 ie 1gb. this is helpful in running programs that require large amount of memory.
but programs that are running on virtual memory are slightly slow because access times of data on a hard disk is more than that of a RAM. so although you may be able to rum a large program but it would'nt run as fast as it would have run if there was 1gb actual RAM.

simulates the action of the hardware RAM, but is just a buffer between a RAM and a hard drive.
