Virtual memory can be defined as a feature of an OS that permits a computer to be ready to compensate for shortages of physical memory by transferring pages of knowledge from random access memory to disk storage.
This process is completed temporarily and is meant to figure as a mixture of RAM and space on the hard disc.
This means that when RAM runs low, virtual storage can move data from it to an area called a paging file. This process allows for RAM to be freed up in order that a computer can complete the task.
Occasionally a user could be viewed a message that states the virtual storage is running low, this suggests that either more RAM must be added, or the dimensions of the paging file must be increased.
