A Floppy Disk is an information storage medium composed of a disk of thin magnetic material, sealed in a rectangular plastic casing.
Proceeding the Compact Disk, Floppy disks can only be read and written by a floppy disk drive (FDD). They were the premiere medium for computer information storage from the 1970's to the mid-2000's where they were replaced by Compact disks and USB flash drives.
