Pages of process memory may be displaced from the RAM to the disk. This is called swapping or paging (the terms are essentially synonymous). The data is moved to the swap space, and loaded back from the swap space when it is needed. Linux supports both partitions (and other block devices) and files ...

Instead of trying to put data into often-limited volatile RAM memory, data is actually written onto the hard disk. Accordingly, the size of virtual memory is limited only by the size of the hard disk, or the space allocated to virtual memory on the hard disk. When information is needed in RAM, the exchanges system rapidly swaps ...
