does not require constant power
Explanation:
Secondary storage (like hard drives, SSDs, CDs, USB drives) is non-volatile, meaning it retains data even when the power is turned off.
- (A) is incorrect because secondary storage does store information for later retrieval.
- (B) is vague and incorrect — the term "main types" isn't specific.
- (C) is incorrect — many secondary storage devices (like hard disks) do use magnetic media.
Thus, the correct characteristic of secondary storage is that it does not require constant power.
