 | | Compared to main memory, secondary memory is slower, bigger, and cheaper (per unit storage.) Any method for secondary storage must involve two physical parts: a peripheral device (the component of the computer which 'reads' in or 'writes' out the information to/from the system unit,) and an input/output medium, on which the information is actually stored. |
 | | In most methods of secondary storage, this transfer is realized by passing the medium by a read/write head, which is capable of sensing/writing information from/to that type of medium. |
 | | Secondary storage media may be removable (easily separable from the computer) like your diskettes, or fixed, like hard disks, which, for example, can be found in relatively expensive PCĂs. |
