Both cache and RAM are volatile memory. The difference between cache and RAM is that the cache is a fast memory component that stores the frequently used data by the CPU while RAM is a computing device that stores data and programs currently used by the CPU. In brief, the cache is faster and expensive than RAM.

Cache is graded as Level 1 (L1), Level 2 (L2) and Level 3 (L3): L1 is usually part of the CPU chip itself and is both the smallest and the fastest to access. Its size is often restricted to between 8 KB and 64 KB. L2 and L3 caches are bigger than L1.

A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because most programs access the same data or instructions over and over.

A cache hit is when an application needs data and finds that data in the cache (a good thing) so it never has to take the slower route and read the disc. A cache miss is when an application needs data and doesn't find it in the cache, so then it has to go and find the data on disc (a bad thing).

Chrome, by default, holds temp files in its cache for a very, very long time. This can make the browser take up an inordinate amount of space on your hard drive.

A cache is a collection of duplicate data, where the original data is expensive to fetch or compute (usually in terms of access time) relative to the cache. In PHP, caching is used to minimize page generation time. PHP basically has two main types of caching: 'output caching' and 'parser caching'.
