Encyclopedic overview
Virtual memory combines active RAM and inactive memory on DASD to form a large range of contiguous addresses.
In computing, virtual memory, or virtual storage, is enabled by a memory management technique that provides an "idealized abstraction of the storage resources that are actually available on a given machine" which "creates the illusion to users of a very large (main) memory".
