Floppy Disk

These are small not fixed disks that are plastic coated with magnetic recording material. Floppy disks are characteristically 3.5″ in size(diameter) and can hold 1.44 MB of data. This moveable storage device is a rewritable media and can be reused many times.

Floppy disks are generally used to move files between different computers. The major disadvantage of floppy disks is that they can be damaged effortlessly and, so, are not very reliable.
