B) search time
C) transfer time
D) delay time

Question

Quizplus · Accepted Answer

The three components of access time in a movable-head DASD are seek time, search time, and transfer time. Seek time is the time it takes for the head to move to the correct track. Search time refers to the time it takes for the head to locate the correct sector on the track. Transfer time is the time it takes for the data to be transferred between the disk and the computer.

Of these three, seek time is typically the slowest as it involves physical movement of the read-write head across the disk surface. Search time and transfer time are typically faster as they do not involve physical movement of the head. Therefore, the best choice for the slowest component of access time in a movable-head DASD is A) Seek time.
