Hardware Prefetching

Hardware prefetching is a computer's way of predicting the data or instructions it will need next and loading them into faster memory before they are actually requested. This proactive approach reduces delays caused by waiting for data from slower main memory, improving overall performance. Think of it as a proactive shopper who gathers items they anticipate needing soon, so they don't waste time searching later. Hardware prefetchers analyze access patterns and pre-load data accordingly, making computer operations smoother and faster without requiring user intervention.
