Web & NetworkingCDN
Content Delivery Network
Short definition
A network of globally distributed servers that delivers your site files from the location closest to each visitor.
Extended definition
A CDN stores copies of your site files (images, CSS, JavaScript) in dozens of locations worldwide. When a visitor in Yemen requests a file, it is served from the nearest edge server (say in Jeddah or Frankfurt), reducing latency from 300ms to 30ms. Cloudflare, AWS CloudFront, and BunnyCDN are the most common providers.
Example & use case
To enable a CDN for your site, point DNS to Cloudflare (free) or upload static assets to AWS S3 + CloudFront.
