Verified Answer
A. (a) Volatile storage
B. (b) Non-volatile storage
C. (c) Sequential storage
D. (d) Direct storage
E. (e) None of these
Explanation:
Option (b) Non-volatile storage is correct because it refers to memory that retains its stored information even when not powered, such as ROM, hard drives, or flash memory. Option (a) Volatile storage, like RAM, loses its data when power is removed. Options (c) Sequential storage (e.g., magnetic tape) and (d) Direct storage (e.g., hard drives, RAM) describe methods of data access, not whether data persists after power loss. Therefore, (e) None of these is incorrect.
