CDN

Updated: 07/14/2017 by Computer Hope

Short for content delivery network or content distribution network, a CDN is a global network that caches static content such as images, CSS, and videos for a website around the world. CDN helps improve the load time of a website by loading the static content from the closest CDN server.

For example, if a website visitor was in India and the webserver was in the United States, each request made by the visitor must travel from India to the United States. Although each request may only be a few hundred milliseconds, a site that makes dozens of different requests can increase a sites overall load time.
