CDN is a program which was designed to avoid latency (the delay to load a page onscreen) which generally occurs due to the physical distance of the user and the main server.
To shorten the distance, the CDN stores the cached version of the page in different geographical locations or PoPs (Points of Presence). Every PoP collects the version to enhance the proximity of the website. In a nutshell, you can say that CDN is a way to reduce the virtual distance between the server and user, speed up the loading time and enhance the user experience.

Every CDN automatically serves the users who are geographically close to them. This way the physical distance between the main server and the users has shorten virtually. CDN improves the transmission speed by creating the cache of all the static data in the region base PoP. But when the cache file is not available in the PoP, it will load the file directly from the main server.
