Answer 1

Explanation:

Auxiliary memory units are among computer peripheral equipment. They trade slower access rates for greater storage capacity and data stability. Auxiliary memory holds programs and data for future use, and, because it is nonvolatile (like ROM), it is used to store inactive programs and to archive data. Early forms of auxiliary storage included punched paper tape, punched cards, and magnetic drums. Since the 1980s, the most common forms of auxiliary storage have been magnetic disks, magnetic tapes, and optical discs.
