Question
MCQ:
Cache is a high speed memory and usually:
1) Dynamic RAM (DRAM)
2) Static RAM (SRAM)
3) SDRAM
4) None of the above
What is Cache memory:
1) A high speed memory
2) Usually a static RAM
3) One of the CPU registers that makes the CPU very fast
4) 1 and 2
In general, we need cache memory because:
1) The time it takes to bring an instruction (or piece of data) from the main memory to the CPU is very fast
2) The time it takes to bring an instruction (or piece of data) from main memory to the CPU is very slow
3) It improve the CPU performance
4) 2 and 3
Explanation / Answer
Q1:
Cache is a high speed memory and usually:
1) Dynamic RAM (DRAM)
2) Static RAM (SRAM)
3) SDRAM
4) None of the above
ANS: 2
Cache is a high-speed memory made of Static RAM.it is faster and expensive than Dynamic RAM.
SRAM is fast and no refresh is required in SRAM.That why it is used to the made Cache memory.

Q3. In general, we need cache memory because:
1) The time it takes to bring an instruction (or piece of data) from the main memory to the CPU is very fast
2) The time it takes to bring an instruction (or piece of data) from main memory to the CPU is very slow
3) It improve the CPU performance
4) 2 and 3
ANS: 4
if we keep data in Cache memory, Computer avoids accessing the slower DRAM. because the time it takes to bring an instruction (or piece of data) from main memory to the CPU is very slow as compared to cache to the CPU. So it overall improves CPU performance also.
