key-point-image Key Points

  • Cache memory is faster than RAM, not slower. This is why the statement "Cache memory is slower than RAM" is incorrect.
  • Cache memory is a small-sized, high-speed memory located closer to the CPU than RAM.
  • It is designed to store frequently accessed data and instructions to reduce the time it takes to fetch them from the slower RAM.
  • Cache memory improves the overall speed and performance of the system by acting as a buffer between the CPU and RAM.
  • It is costlier than RAM due to its higher speed and complexity.

additional-information-image Additional Information

  • Cache memory is divided into levels (L1, L2, L3), where L1 is the fastest and smallest, and L3 is the slowest and largest among the cache levels.
  • Modern processors use cache memory extensively to optimize performance and reduce latency.
  • While cache memory is faster than RAM, it is much smaller in capacity, which limits the amount of data it can store.
  • The use of cache memory significantly enhances the speed of repetitive tasks by storing frequently accessed data closer to the CPU.
