Question

Which of the following acts as a buffer between the CPU and the main memory?

• A. primary memory
• B. cache memory
• C. secondary memory
• D. RAM

Hint:

Cache memory is faster than RAM and is used to reduce the time the CPU takes to access data from the main memory.

Answer 1

The Correct Option is B

Cache memory acts as a buffer between the CPU and the main memory. It is a small, fast memory located closer to the CPU that stores frequently accessed data to speed up processing. By storing commonly used instructions and data, cache memory reduces the time it takes to access the main memory, improving the overall performance of the system. Thus, the correct answer is (b) cache memory.
