Data Storage

In a computer, data storage is the place where data is held in an electromagnetic or optical form for access by a computer processor.

Storage is frequently used to describe the devices and data connected to the computer through input/output (I/O) operations -- that is, hard disk and tape systems and other forms of storage that don't include computer memory and other in-computer storage. For the enterprise, the options for this kind of storage are of a much greater variety and expense than those related to memory.
