The correct answer is: C. Paper tape
A magnetic disk is a data storage device that uses magnetic storage to store and retrieve digital information. It is a thin, circular plate with a magnetic coating on one or both sides. The data is stored on the disk in the form of tiny magnetic spots.
A magnetic tape is a data storage medium that consists of a long, thin strip of magnetic material coated on a plastic backing. The tape is wound on a reel and can be read and written by a magnetic tape drive.
Paper tape is a data storage medium that consists of a long, thin strip of paper with holes punched in it. The holes represent binary data, which can be read and interpreted by a paper tape reader.
Paper tape is not a sequence storage device because the data is not stored in a linear order. The holes in the paper tape can be punched in any order, and the reader can read the data in any order.
Magnetic disks and magnetic tapes are sequence storage devices because the data is stored in a linear order. The data is stored on the disk or tape in a series of tracks, and the tracks are read in order.
