F - correct-answer-During a read or write operation, the head rotates while the platter
beneath it stays stationary.
(T/F)
F - correct-answer-The width of a track is double that of the head. (T/F)
T - correct-answer-There are typically hundreds of sectors per track and they may be
either fixed or variable lengths.
(T/F)
T - correct-answer-A bit near the center of a rotating disk travels past a fixed point
slower than a bit on the outside.
(T/F)
F - correct-answer-The disadvantage of using CAV is that individual blocks of data can
only be directly addressed by track and sector.

T - correct-answer-A removable disk can be removed and replaced with another disk.
(T/F)
T - correct-answer-The head must generate or sense an electromagnetic field of
sufficient magnitude to write and read properly.
(T/F)
F - correct-answer-The transfer time to or from the disk does not depend on the
rotation speed of the disk.
(T/F)
T - correct-answer-RAID is a set of physical disk drives viewed by the operating system
as a single logical drive.
(T/F)
T - correct-answer-RAID level 0 is not a true member of the RAID family because it
does not include redundancy to improve performance.
