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
41. A major disadvantage of the mask ROM is that it:
- is time consuming to change the stored data when system requirements change
- is very expensive to change the stored data when system requirements change
- cannot be reprogrammed if stored data needs to be changed
- has an extremely short life expectancy and requires frequent replacement
42. The periodic recharging of DRAM memory cells is called ________.
- multiplexing
- bootstrapping
- refreshing
- flashing
43. Which of the following is normally used to initialize a computer system's hardware?
- Bootstrap memory
- Volatile memory
- External mass memory
- Static memory
44. What is the difference between static RAM and dynamic RAM?
- Static RAM must be refreshed, dynamic RAM does not.
- There is no difference.
- Dynamic RAM must be refreshed, static RAM does not.
45. Microprocessors and memory ICs are generally designed to drive only a single TTL load. Therefore, if several inputs are being driven from the same bus, any memory IC must be ________.
- buffered
- decoded
- addressed
- stored
47. How many address bits are required for a 4096-bit memory organized as a 512 × 8 memory?
