A diskette is a flexible plastic disc coated with ferromagnetic particles, which enables the recording, erasing and reading of information on its surface by means of an electromagnetic head. They are protected by a plastic cover that is more rigid to avoid contact with the outside. These disks are of the portable type and allow the transference of information from one computer to another. There have been many sizes and capabilities through its evolution. This technology was introduced commercially in computers in 1971 by IBM. The use of floppies, as they are also known, is practically obsolete now.
