virtual memory



Virtual memory is one of the feature of Operating system, It is an way to make use of the secondary storage devices as an extension of the primary 
storage of the computer.

It is the process of increasing the size of a computer's RAM by using a section of the hard 
disk storage as an extension of RAM.

Logically-assigned memory that may or may not exist physically. Through the use of paging and the swap area, more memory can be referenced and allocated than actually exists on the system, thus giving the appearance of a larger main memory than actually exists.
