Question

In disk organization, the time taken by the head to reach the beginning of sector is

• A. Seek time
• B. Access time
• C. Track time
• D. Rotational delay

Hint:

Rotational delay refers to waiting time for the disk to spin to the correct sector.

Answer 1

The Correct Option is D

Rotational delay (or latency) is the time taken by the disk to rotate the desired sector under the read-write head. It is different from seek time which is the time to move the head to the correct track.
