Definition
A CDN is a network of servers distributed globally that delivers cached content to users based on their geographic location. It reduces page load times, handles traffic spikes, and improves security.
Example
When a user in London requests your page, a CDN serves it from a London server instead of your US server — reducing load time from 3 seconds to 0.5 seconds.
