A floppy disk or diskette is a kind of computer storage medium used to store small amounts of data.
A diskette is consisted of a film placed in a plastic case.
The film is covered with a thin layer of particles capable of getting magnetized.
The read/write mechanism of a floppy disk is identical to that of a hard disk and is carried out through a drive containing a head (for data read/write).
Diskettes should be stored in place away from heat and strong magnetic fields as these two factors could destroy saved data.
Diskettes are old technology storage mediums and are no longer used.
