The cache is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache memory is small and works much faster than both system memory and other levels of cache memory. If the processor does not find the requested data in L1, it continues to search for them in the L2 cache. With some processors, this search is performed simultaneously in L1 and L2.

L2 (level 2) cache is slower than L1, but instead it has a large capacity, allowing caching of more data. She, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to search for them in the L3 cache (if any) or in the RAM memory.

L3 (level 3) cache is slower than L2, but instead it has a large capacity, which allows caching more data. It, like L2, is much faster than system memory (RAM).

The processor core executes program instructions. There are processors with one, two or more cores. Having more cores increases performance by allowing multiple instructions to execute in parallel.
