'''Secondary storage''' refers to all forms of data storage other than [[main memory]]; data in secondary storage generally had to be brought into main memory before it can be operated upon.

Over time there have been many forms of secondary storage: [[magnetic tape]] is one of the oldest, and is still in use today. [[Disk]]s are almost as old, and again, still in use (although the rise of solid state mass storage such as [[SD memory cards]] may make them obsolete).

There are a number of types which are now obsolete: [[punched cards]], [[paper tape]], etc.
