In theory, CDN or Content Delivery Network when spelled in full, is the transparent backbone of the digital space in charge of delivering all kinds of content.

However, it’s safe to say that delays are affected by the physical distance between a website’s organ server and your present location.

How does a CDN function? | CDN definition
To reduce the physical distance between a site’s server and its online visitors, a CDN keeps a cached version of the content found on these sites. CDNs then store them in several geographical spots, also referred to as PoPs or Points of Presence. Every PoP keeps a series of caching servers that handle the delivery of content to its users within a given region.
Essentially, what a CDN does is store your content all at once in multiple places, making sure only superior content coverage reaches your visitors. To depict clearly, say, someone from Australia accesses your America-hosted site, that’s achieved with the help of a local Australian PoP. This kind of process is a lot simpler compared to having your responses and a user’s requests travel all the way from several seas and then back.
In a nutshell, that’s how a CDN helps businesses. Of course, this article doesn’t stop there. Because how it works is really just the tip of the iceberg, there are other things you should know about it.
