Hai

When we use the application goes to over the RAM capability some amount of space in the HDD act as a RAM for  managing the application.that is called Virual memory.
if the system running in virtual memory it is slow than RAM based running.bcoz if you are working in the virtual memory, the process will be running based on only via RAM .

With virtual memory, the computer can look for areas of RAM that have not been used recently and copy them onto the hard disk. This frees up space in RAM to load the new application. Because it does this automatically, you don't even know it is happening, and it makes your computer feel like is has unlimited RAM space even though it has only 32 megabytes installed. Because hard-disk space is so much cheaper than RAM chips.
