A concrete explanation of how a cache works

https://parksb.github.io/images/54875045-80f32980-4e3a-11e9-8854-5cef63c9c58e.webp
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 chip. (It’s also expensive.) Going to main memory for data every time is slow, so the cache holds ...
