Show answer & explanation
Correct answer: C
Concept
Computer memories are classified independently by their position and speed in the memory hierarchy and by their ability to retain data. Cache is a small, very fast memory close to the processor; RAM is the working primary/internal memory, while ROM is non-volatile storage.
Volatility asks whether stored data survives removal of power. This property is separate from whether a memory is read-mostly or writable.
Application
Statement I places RAM in internal memory and compares its access time with cache. RAM is internal or primary memory, and cache has lower access time than RAM; therefore Statement I is true.
Statement II says ROM loses its data when power is removed. Standard ROM is non-volatile and retains its stored contents; therefore Statement II is false.
Cross-check and contrast
Statement | Governing property | Evaluation |
|---|---|---|
Statement I | Cache has lower access time than internal/primary RAM. | True |
Statement II | ROM retains stored data when power is removed. | False |
“Both statements are true” treats ROM as volatile, which confuses power retention with read-only operation.
“Both statements are false” ignores RAM’s place in internal memory and the lower access time of cache.
“Statement I is false but Statement II is true” reverses both properties.
Therefore, Statement I is true and Statement II is false.
