CDN (Content Delivery Network)

A CDN is a globally distributed network of servers that caches and delivers web content from locations geographically close to users.

Instead of serving files from a single origin server, a CDN stores copies of static content (HTML, CSS, JavaScript, images) in multiple edge locations worldwide. When a user requests a page, the content is delivered from the nearest edge server, reducing latency and improving performance.

This means users access content from the closest available edge location rather than a single centralized server.
