Answer 2

Answer:

1. A floppy disk or floppy diskette (sometimes casually referred to as a floppy or diskette) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. Floppy disks are read from and written to by a floppy disk drive (FDD).
2. Output Interface Unit:Output interface unit is also a type of interface unit which is used in computer system to convert digital signals into analog signals. It converts computational signals used by the computer system into the user signals.

• Input-Output interface provides a method for transferring information between internal storage (such as memory and CPU registers) and external I/O devices. Peripherals connected to a computer need special communication links for interfacing them with the central processing unit.
