Q22
Which of the following is not an advantage of magnetic disk storage?
A.
The access time of magnetic disk is much less than that of magnetic tape
B.
Disk storage is less expensive than tape storage
AnswerC.
Disk storage is longer lasting than magnetic tape
D.
None of the above
Answer: Option B
Solution
Answer: Option B
Solution:
Option B is not an advantage of magnetic disk storage because: Magnetic disk storage tends to be more expensive than magnetic tape storage, especially when comparing cost per unit of data storage.
Magnetic tapes are generally used for cost-effective long-term storage and archival purposes, whereas magnetic disks offer faster access times and are used for active storage.
Therefore, stating that disk storage is less expensive is incorrect, making Option B the right choice as it is not an advantage of magnetic disk storage.
