Question

The tracks on a disk which can be accessed without repositioning of read write head is ___________.

• A. Surface
• B. Cylinder
• C. Cluster
• D. All of the above

Answer 1

Answer: (B)

Cylinder

The tracks on a disk which can be accessed without repositioning of read write head is Cylinder.

Cylinders are vertically formed by tracks. In other words, track 12 on platter 0 plus track 12 on platter 1 etc. is cylinder 12. The number of cylinders of a disk drive exactly equals the number of tracks on a single surface in the drive. So, in order to access a particular cylinder from a track we do not need to move read write head from that particular track.
