So when a user access a blog or article from any website, that web site could be the host on any web hosting service like Hostgator, BlueHost or SiteGround. Let’s assume that the site is hosted on Hostgator and Hostgator has the Data Server in Texas. So now when the user accesses the website from the UK so the user can face slowness or latency due to many hopping on internet

So the is where CDN comes into the picture.

How CDN Works ?

CDN is a network of serves which are spread across the globe. Thus CDN stores the static content like images, CSS (Cascading Style Sheets), PDF, JavaScript. So now hen the user visits the site from different Geographical region CDN redirects him to the closest caching server to their location.

The globally caching of the content reduces the distance between the user and website content.  SO the user instead connect to the Origin server CDN allows the user to connect to nearest server thus the website loads faster and the user gets a quick service.

Caching servers has the Optimized Hardware and Software efficient load balancing with SSD (Solid State Hard Disks)
