What is Content Delivery Network(CDN)?

CDN Intro:

Content Delivery Network Used to increase a speed of the website. CDN will analyze the user and stores files such as Javascript and CSS(Cascading Style Sheet) in their local devices.So, it will reduce the load page time. It will only store the JS, CSS, Images because those are likely to be static content. For Example in Live Cricket score website, It will not store any HTML pages or PHP pages. Because that causes users need to refresh every time their web page. For those kinds of issues, It will store only static contents. In 3rd Generation, It stores Static, Dynamic, Rich media and Mobile too.
