How does cache memory improve computer performance?

Cache memory improves computer performance by reducing the time it takes for the processor to access data from the main memory. It works by storing frequently accessed instructions and data closer to the processor, ensuring faster retrieval speeds. When the processor looks for data, it first checks the cache memory. If the requested data is already present in the cache, it can be retrieved almost instantaneously. This eliminates the need to access the slower main memory, which would have caused delays in execution. By reducing memory latency and enhancing data access speed, cache memory enables the processor to operate at a higher speed and improves overall system performance.
