Cache memory reduces average memory access time by exploiting the principle of locality.

Question

Quizplus · Accepted Answer

Cache memory stores frequently accessed data and instructions closer to the processor, thus reducing the time taken to access them from main memory. This is based on the principle of locality, which states that programs tend to access a small portion of their address space with high frequency. By exploiting this principle, cache memory can significantly reduce the average memory access time.
