  • Some examples of the secondary storage devices (an additional memory used to hold a large amount of information outside the Main memory) are: hard disk, CD, Zip, flash drive, and floppy disk.
  • Secondary memory is used to hold numbers, characters, and information as opposed to cassette tapes.
  • Another name for the hard disk is the fixed disk.
  • A hard disk holds more information than a floppy disk, or flash disk, and the capacity is measured in GB.
  • Zip disk is used primarily as a backup.
  • Flash drive is found to be resistant to scratches, dust, breaks, or mechanical failure.
  • The floppy disk is sealed inside a jacket as a protective coat in a square shape.
  • Diskettes used to be the media through which we collect data, for subsequent transfer to another system. It has become obsolete, out-of-date, and old-fashioned.
