Secondary Storage

Secondary storage device

Alternatively referred to as external memory and auxiliary storage, secondary storage is a storage medium that holds information until it is deleted or overwritten regardless if the computer has power. For example, a floppy disk drive andhard drive are both good examples of secondary storage devices. As can be seen by the below picture there are three different storage on a computer, although primary storage is accessed much faster than secondary storage because of the price and size limitations secondary storage is used with today's computers to store all your programs and your personal data.

Finally, although off-line storage could be considered secondary storage, we've separated these into their own category because this media can be removed from the computer and stored elsewhere.
