What Is The Difference Between A Caching Plugin And A CDN?

Hi, welcome to Hopps help where we answer questions in two minutes. Today's question is what is the difference between a caching plugin and a CDN?
So, a caching plugin such as w three total cash, the content on your server. So, let's say that you have a page that needs to be compiled from various plugins, that, that contribute to the page such as maybe you have a Google ad running on there.
And another one is a contact form. So those all need to be created through the server, but to speed things up, your server can go and cash.
The HTML output. What you see is called HTML by the way. So that gets cashed in the server and it speeds up the page load because it doesn't have to go and recompile that output.
It just sends it from the cash. Now a CDN, however, is where you take in data from maybe a third-party URL or something of that nature.
Now, if you have bootstrap on your website, which is a popular JavaScript level library, and it could be anything I'm just using that.
As an example, you have that you have made the bootstrap CSS file, or maybe you have a J query or something of that nature.
Something that every site is going to be using practically, there's a very good chance that somebody has already loaded that library.
I'm one of these sites, every single site loaded their own copy of that library. It would go in; they'd have to load it every single time they visit the site.
Now, if they have it from the same URL, the browser says, I've already loaded this URL. Why don't I just go and use that for this site as well?
And that's the beauty of a CDN means you load it on the load it from a CDN and other sites using that CDN can go and leverage that, that already loaded code.
