Final answer:
The correct term for the time it takes for a disk drive's read/write head to position itself over a specified track is 'seek time.' This term specifically pertains to the movement of the head to the correct track and is distinct from access time and latency.
Step-by-step explanation:
The time it takes for the read/write head of a disk drive to get into position over a specified track is known as the seek time. The seek time specifically refers to the time duration for the hard drive’s read/write head to move and align itself with the track where the data needs to be read from or written to. This is different from access time which also includes the latency, or the time it takes for the sector to be accessed to rotate into position under the read/write head after it has arrived at the correct track. The transfer rate is the speed at which data can be transferred to or from the disk but does not relate to the movement of the read/write head. Therefore, the correct answer to the question is A. seek time.
