The purpose of storage hardware is to store computer instructions

Storage hardware The purpose of storage hardware is to store computer instructions
and data in form that is relatively permanent and. 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 (HDD), 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) – a thin, usually flexible plastic disk coated with magnetic material, for storing temporary computer data and programs. There are two formats for floppy disks: 5.25” and 3.5”. 5.25” is not used in modern computer systems because of it relatively large size, flexibility and small capacity. 3.5” disks are formatted 1.44 megabytes and are widely used.
3.5’ disks are formatted 1.4 megabytes and are widely used.
CD-ROM (compact disk read only memory) is a compact disk on which a large amount of digitized read-only data can be stored. CD-ROMs are very popular now because of the growing speed which CD-ROM drives can provide nowadays.
