Access to moving head disks requires three periods of delay before information is brought into memory. The response that correctly lists the three time delays for the physical access of data in the order of the relative speed from the slowest to the fastest is
| A. | latency time, cache overhead time, seek time |
| B. | transmission time, latency time, seek time |
| C. | seek time, latency time, transmission time |
| D. | cache overhead time, latency time, seek time |
Answer : C Explanation : Seek time is the time required to move the disk arm to the required track. Rotational delay or latency is the time it takes for the beginning of the required sector to reach the head. Sum of seek time (if any) and latency is the access time. Time taken to actually transfer a span of data is transfer time or transmission time. |
