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
1. How many address bits are needed to select all memory locations in the 2118 16K × 1 RAM?
- 8
- 10
- 14
- 16
2. The check sum method of testing a ROM:
- indicates if the data in more than one memory location is incorrect.
- provides a means for locating and correcting data errors in specific memory locations.
- allows data errors to be pinpointed to a specific memory location.
- simply indicates that the contents of the ROM are incorrect.
3. What is the meaning of RAM, and what is its primary role?
- Readily Available Memory; it is the first level of memory used by the computer in all of its operations.
- Random Access Memory; it is memory that can be reached by any sub- system within a computer, and at any time.
- Random Access Memory; it is the memory used for short-term temporary data storage within the computer.
- Resettable Automatic Memory; it is memory that can be used and then automatically reset, or cleared, after being read from or written to.
4. The storage element for a static RAM is the ________.
- diode
- resistor
- capacitor
- flip-flop
5. In a DRAM, what is the state of R/W during a read operation?
- Low
- High
- Hi-Z
- None of the above
6. The condition occurring when two or more devices try to write data to a bus simultaneously is called ________.
- address decoding
- bus contention
- bus collisions
- address multiplexing
7. Which is/are the basic refresh mode(s) for dynamic RAM?
- Burst refresh
- Distributed refresh
- Open refresh
- Burst refresh and distributed refresh
8. One of the most important specifications on magnetic media is the ________.
- rotation speed
- tracks per inch
- data transfer rate
- polarity reversal rate
10. The reason the data outputs of most ROM ICs are tristate outputs is to:
- allow for three separate data input lines.
- allow the bidirectional flow of data between the bus lines and the ROM registers.
- permit the connection of many ROM chips to a common data bus.
- isolate the registers from the data bus during read operations.
