Caching is the practice of storing recent results and reusing them when possible. It is a common computing design that is often build into services, applications, clients such as web browsers, operating systems and hardware devices such as CPUs and data storage devices. In many cases, a cache is held on a faster type of technology than the original data. For example, images accessed over a network may be cached on a local disk to improve web browsing speed. Beyond access speed, caches may include things that were time consuming to compute such as the results of a complex algorithm.
