Cache locality refers to the practice of organizing data in memory to minimize cache misses and improve performance by taking advantage of the hierarchical nature of modern memory systems. It exploits both temporal locality, where recently accessed data is likely to be accessed again soon, and spatial locality, where data located close to recently accessed data is likely to be accessed soon.

Performance improvement is a systematic process aimed at enhancing the efficiency and effectiveness of an organization or individual by identifying performance gaps and implementing strategies to close them. It involves continuous assessment, feedback, and adaptation to achieve optimal results and sustain long-term success.

Temporal locality is a principle in computer science where recently accessed data is likely to be accessed again in the near future. It is a crucial aspect of optimizing cache performance by predicting which data to keep in cache to improve processing efficiency.

Spatial locality refers to the tendency of a program to access data locations that are close to each other within a short time period. This principle is leveraged in computer systems to optimize performance by loading data into cache lines that contain not just the requested data, but also adjacent data likely to be used soon.
