6. Cache Memory and Its Impact on System Performance

Cache memory serves as a high-speed storage area that enables faster access to frequently used data by acting as a buffer between the CPU and main memory. Its various characteristics, levels, mapping techniques, replacement policies, and performance metrics are crucial for understanding how cache can significantly enhance system performance and efficiency. The impact of cache design is critical for optimizing CPU throughput and reducing bottlenecks in modern computing systems.
