A floppy disk was a removable, magnetic data storage medium used in early computers, consisting of a flexible magnetic disk enclosed in a plastic jacket. The term "floppy" referred to the flexible disk inside, though later versions had rigid cases. Floppy disks were used for storing files, distributing software, and transferring data before being replaced by more modern media like CD-ROMs and USB drives.

Key features and function

Storage: A thin, flexible platter coated with magnetic material was the core of the disk, with data written to it by a read/write head in the computer's floppy disk drive.

Removable: They were a form of "portable" storage, allowing users to move data between computers or to create backups.

Durability: Early 8-inch disks were in flexible sleeves, while later 5.25-inch and 3.5-inch versions were more durable due to their more rigid jackets.

Replaced by: As technology advanced, they were phased out in favor of CD-ROMs, DVDs, and USB drives, which offered larger capacities and better speed.
