Show answer & explanation
Correct answer: B
The total time to access a disk block consists of three components:
Seek Time
Time taken to move the read/write head to the desired track
Rotational Delay (Latency)
Time waiting for the required sector to rotate under the head
Transfer Time
Time taken to actually read/write the data
Therefore:
Total Access Time=Seek Time + Rotational Delay + Transfer Time
