Memory and Storage Questions and Answers
Memory and Storage Questions with Answers are an integral part of digital electronics aptitude and technical competitive exams. This topic focuses on types of memories—RAM, ROM, Cache, and Flash—and their roles in data processing and system performance. Students preparing for GATE, ISRO, DRDO, or PSU exams often encounter questions that test conceptual understanding of primary vs. secondary storage, memory hierarchy, and data access methods. Practicing aptitude questions with solutions PDF on Memory and Storage helps learners build strong analytical reasoning about digital systems. These aptitude-based problems come with detailed explanations to strengthen your conceptual clarity and enhance speed during exams. Start your aptitude test practice online to confidently solve memory and storage-related questions in any electronics or computer engineering placement test.
Memory and Storage

15. Why are ROMs called nonvolatile memory?
- They lose memory when power is removed.
- They do not lose memory when power is removed.
