What is Content Delivery Network (CDN)

A CDN is a content delivery network. It means that whenever you request a web page on the internet by typing the URL in the web browser, the content of that web page is stored in a variety of distributed servers in the form of static files such as style sheets, scripts etc. These are then retrieved from these distributed locations and displayed on your web browser. In this infographic titled, “What Is CDN,” you will see what happens in the background when you click on a web page.

The data of a web page is distributed across many servers across the world. That is one of the reasons no matter in which country you are, you can always view a web page. So, if you request a web page from a browser, then that request goes through a variety of distributed network servers and the requested page is displayed on the browser to the end user.

The distributed servers contain content such as text, images, graphics, mixed media, etc that are present on the webpage. This helps in creating a better SEO experience as the content is distributed. CDN is also one of the reasons why your web pages loads quickly. If there are too many images or videos on a web page then the load time varies. Overall anyone interested in web technologies will certainly find this useful.
