Hierarchy Of Memory

Computer Organization Questions and Answers – Heirarchy Of Memory

This set of Computer Organisation and Architecture MCQ focuses on “Memory Hierarchy”.

1. The standard SRAM chips are costly as
a) They use highly advanced micro-electronic devices.
b) They house 6 transistor per chip.
c) They require specially designed PCB’s.
d) None of the above.
View Answer

Answer:b
Explanation: As they require a large number of transistors, their cost per bit increases.

2. The drawback of building a large memory with DRAM is
a) The large cost factor.
b) The inefficient memory organisation.
c) The Slow speed of operation.
d) All of the above.
View Answer

Answer:c
Explanation: The DRAM’s were used for large memory modules for a long time until a substitute was found.

3. To overcome the slow operating speeds of the secondary memory we make use of faster flash drives.
a) True
b) False
View Answer

Answer:a
Explanation: To improve the speed we use flash drives at the cost of memory space.

4. The fastest data access is provided using _______.
a) Caches
b) DRAM’s
c) SRAM’s
d) Registers
View Answer

Answer:d
Explanation: The fastest data access is provided using registers as these memory locations are situated inside the processor.

5. The memory which is used to store the copy of data or instructions stored in larger memories, inside the CPU is called _______.
a) Level 1 cache
b) Level 2 cache
c) Registers
d) TLB
View Answer

Answer:a
Explanation: These memory devices are generally used to map onto the data stored in the larger memories.

6. The larger memory placed between the primary cache and the memory is called ______.
a) Level 1 cache
b) Level 2 cache
c) EEPROM
d) TLB
View Answer

Answer:b
Explanation: This is basically used to provide effective memory mapping.

7. The next level of memory hierarchy after the L2 cache is _______.
a) Secondary storage
b) TLB
c) Main memory
d) Register
View Answer

Answer:d
Explanation: None.

8. The last on the hierarchy scale of memory devices is ______.
a) Main memory
b) Secondary memory
c) TLB
d) Flash drives
View Answer

Answer:b
Explanation: The secondary memory is the slowest memory device.

9. In the memory hierarchy, as the speed of operation increases the memory size also increases.
a) True
b) False
View Answer

Answer:b
Explanation: As the speed of operation increases the cost increases and the size decreases.

10. If we use the flash drives instead of the harddisks, then the secondary storage can go above primary memory in the hierarchy.
a) True
b) False
View Answer

Answer:b
Explanation: The flash drives will increase the speed of transfer but still it wont be faster than primary memory.
