The purpose of storage hardware is to store computer instructions and data in a form that is relatively permanent and retrieve when needed for processing. Storage hardware serves the same basic functions as do office filing systems except that it stores data as electromagnetic signals. The most common ways of storing data are hard disk, floppy disk and CD-ROM.
Hard disk is a rigid disk coated with magnetic material, for storing programs and relatively large amounts of data.
Floppy disk (diskette) – thin, usually flexible plastic disk coated with magnetic material, for storing computer data and programs.
CD-ROM (compact disc read only memory) is a compact disc on which a large amount of digitized read-only data can be stored.
