Content Delivery Network — infrastructure for delivering streaming video globally.

Explanation

A CDN (Content Delivery Network) is a geographically distributed network of servers that delivers video content to users from the server closest to them. Netflix operates its own CDN called Open Connect, while other services use commercial CDNs like Akamai, Cloudflare, or AWS CloudFront. CDNs reduce latency and buffering.
