Correct AnswerA. nonvolatile memory
Quick Explanation
ROM retains its stored information without electrical power, so it is nonvolatile memory. It is primarily intended for fixed or infrequently changed code/data rather than ordinary volatile working storage. Therefore option A is correct.
Detailed Explanation
Correct Answer
A — nonvolatile memory
Concept and Reasoning
ROM retains its stored information without electrical power, so it is nonvolatile memory. It is primarily intended for fixed or infrequently changed code/data rather than ordinary volatile working storage. Therefore option A is correct.
Calculation / Key Relation
ROM retains data when power is removed
Exam Takeaway
ROM = nonvolatile storage.
Common Mistake
Do not classify ROM as volatile RAM merely because both are semiconductor memories.
