A very concrete explanation of how a cache works
KO | EN As technology has advanced, processor speed has risen quickly, but memory speed hasn’t kept up. No matter how fast a processor is, if memory responds slowly the whole system ends up slow. The device that addresses this is the cache. A cache is a small, fast memory that sits inside the CPU ch...
