Question 3

Assertion (A): Cache memory is placed between CPU and main memory (RAM).

Reasoning (R): Cache memory stores frequently used data and instructions so that they are immediately available to the CPU.

  1. Both A and R are true and R is the correct explanation of A.
  2. Both A and R are true but R is not the correct explanation of A.
  3. A is true but R is false.
  4. A is false but R is true.
Answer

Both A and R are true and R is the correct explanation of A.

Explanation
Cache memory is placed between the CPU and the main memory (RAM) to store frequently used data and instructions. By doing so, it makes this data available to the CPU very quickly, sending it directly to the CPU instead of the main memory. This significantly reduces access time, thereby improving the overall performance of the computer.
