The cache can look a lot like the Matrix, it’s everywhere and nowhere. It’s in our favorite web browsers, on all of our devices, routers, on our servers, and it runs on our websites. The cache can even be the basis of the methodology for CDN (Content Delivery Network). Without the different caching elements, the Internet would make DSL look like a 14.4K dial-up modem that came before ISDN that we thought would dominate the web. This article is intended to provide a basic understanding of what caching is, how it works, and its relevance.

Caching is very common and can sometimes get confusing when trying to understand the different methods behind how it works and how it can be used in the many different ways that help make the web a better and more user-friendly place. . Wiki defines cache as a component that stores data so that future requests for that data can be served much more quickly.

Servers use caching to help reduce CPU usage and load. Web browsers use a cache to display website pages faster for users, so they don’t have to wait as long for the website page to load. Routers cache the Internet protocols of DNS to send and receive those requests faster so that web browsers can operate at a higher level of performance. CDNs are created and designed using caching in ways that you think are unheard of. Although most CDNs don’t cache HTML files that shouldn’t be needed in the first place, they do cache many elements that HTML uses.

When it comes to websites, caching will always be one of the most critical in making web pages load faster. All other caching items take that speed and increase it. As you may or may not know, it is a good idea to clear your web browser’s cache from time to time. Web browsers are getting better at removing a regulated amount more frequently by clearing the cache after a certain period of time, but they always keep enough to make your web browsing enjoyable by remembering the pages you visit. A copy of the cache is kept in reserve, so it will appear faster if you visit that same page again and without having to wait so long for it to load. Microsoft’s antivirus software does this normally by default.

In a unique way, caching helps the internet world run a little more smoothly, by helping website pages load faster for people who visit web pages frequently and can also reduce CPU usage at the same time.
