It functions by saving cached, temporary copies of files like images, videos, and scripts on regional servers, which then serve those files directly to nearby users. By eliminating the need for every web request to travel back to a website's primary host server, a CDN dramatically reduces latency and ensures a fast, stable browsing experience.
