In a clear sense, every website available on the internet is hosted to a particular server located at a particular geographical location. So, when a user request for a page to that server, they have only one space available to pull the resources.

1. How a CDN works

Basically, the loading speed of a web page depends very much on the actual distance between the originating server and the site viewer. Along with that, the page speed can be affected if the website is rich in content such as high-quality images, videos, and many others.  So, what CDN basically does is that it allows the relevant files of a particular website cached and stored on multiple local servers situated at different geographical data centers across the globe.

These data centers are also known as points of Presence (PoPs) are optimized to communicate with the site viewer closet to them, so, when a user request for a page, their request will be not be sent directly to the main server, but rather than to these CDN PoPs. Well, this improves the loading speed of the page exponentially.
