A cache server is a dedicated server that saves content in order to expedite data when that content is recalled. A cache server is used, for example, on the internet, to store web pages and other content for future reference. Then if that data is requested in the future, it can be recalled more quickly than if it were to be looked up from scratch. If the data being requested is already stored in the cache, it’s faster to simply read it from the cache than to have to go all the way back to its original storage location in order to find it. Given the brevity of this discussion, only generalized information on cache servers is presented here.
A cache server isn’t necessarily always a web application. It can be applied in other areas, too. For example, there are also CPU caches on computers and disk caches for a computer’s main memory. A cache really just refers to any transparently stored files that are held there for the express purpose of speeding up the recall of these recently used documents. Typically, as more documents are added to the cache, older documents are shoved out. Caches are typically small for the sake of efficiency, making it necessary to shove out old information periodically.
A cache server is also usually a proxy server, or a server that acts on behalf of the user. It can intercept internet requests and manages them to make them as efficient as possible, which means that data recall is also expedited. We live in an age where everybody wants what they’re looking for instantly. If a page takes a few seconds to load, it can elicit groans of frustration and impatience from the viewer. It’s a good thing that caching data can speed up the process of data recall on the internet. We don’t have to wait anymore.
For the most part, typical consumers have access to cache servers. Your computer will already come equipped with the programming to create a cache, and most web browsers have caches already written into their codes as well. To enjoy the benefits of caching is to start looking up content and requesting data so that your cache starts filling up with information. Once it’s full, recalling that information will be a breeze and you’ll be able to surf the internet and get the information you need faster than you ever thought possible.
