Cache lines

A cache line is a small, fixed-sized block of data stored temporarily in your computer's cache memory, which is a high-speed storage area close to the processor. When the CPU needs data, it retrieves it from the cache first, rather than slower main memory. Cache lines improve efficiency by loading a chunk of data at once, anticipating that nearby data will be needed soon. This reduces the time it takes for the CPU to access information, speeding up overall system performance. In essence, cache lines are the building blocks of fast, efficient data retrieval in your computer.
