Magnetic disks are the most popular medium for

  • A.Direct access
  • B.Sequential access
  • C.Both of above
  • D.None of above

Answer: C

Correct answer: Both of above

A magnetic disk supports both. Its read-write head can be positioned on any track, so any record can be reached directly in about the same time; and records can equally be read one after another in order, which is sequential access. That combination is what made the disk displace magnetic tape, which allows sequential access only.
