Question

How is secondary memory different from primary memory?
Options
A Secondary memory is volatile, while primary memory is non-volatile.
B Secondary memory is not directly accessible by the CPU and stores data permanently.
Correct Answer
C Secondary memory is faster and more expensive than primary memory.
D Secondary memory is part of the CPU, while primary memory is external.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Secondary memory (or auxiliary storage) is not directly accessible by the CPU. It is used to store data and programs permanently, retaining information even after the power is turned off. Primary memory (like RAM) is directly accessible and volatile.

Hint

Think about long-term, non-volatile storage versus short-term, fast-access memory.
