In C-LOOK disk scheduling, after servicing the last request in one direction, where does the disk head move?

Options

  • A. To the physical end of the disk
  • B. To the first pending request at the opposite end
  • C. To the nearest pending request only
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. To the first pending request at the opposite end

Detailed Explanation

Explanation: C-LOOK is the circular version of LOOK. The head services requests in one direction until the last pending request in that direction, then jumps to the first pending request at the opposite end and continues in the same direction. It does not travel to the physical end of the disk unnecessarily.
