RAM disk:  RAM that is reconfigured to work like a very high speed disk drive.

The system uses a RAM disk just as it does any other disk drive.  But since a RAM disk is not a true magnetic storage device, its contents are lost when the computer is rebooted.  Any permanent files must be copied from a RAM disk to permanent storage before turning off or rebooting the computer.
