A.
Any point on a Direct Access Storage Device may be promptly reached, whereas every point in between the current position and the desired position of a Sequential Access Storage Device must be traversed in order to reach the desired position

B.
Any point on a Sequential Access Storage Device may be promptly reached, whereas every point in between the current position and the desired position of a Direct Access Storage Device must be traversed in order to reach the desired position

C.
Some tape drives have minimal amounts of Direct Access intelligence built in

D.
Tape drives are Sequential Access Storage Devices

Explanation:
The key distinction between Direct Access and Sequential Access storage
devices is that any point on a Direct Access Storage Device may be promptly reached,
whereas every point in between the current position and the desired position of a
Sequential Access Storage Device must be traversed in order to reach the desired
position. Tape drives are Sequential Access Storage Devices. Some tape drives have
minimal amounts of Direct Access intelligence built in. These include multitrack
tape devices that store at specific points on the tape and cache in the tape drive
information about where major sections of data on the tape begin, allowing the tape
drive to more quickly reach a track and a point on the track from which to begin the
now much shorter traversal of data from that indexed point to the desired point.
While this makes such tape drives noticeably faster than their purely sequential
peers, the difference in performance between Sequential and Direct Access Storage
Devices is orders of magnitude.
