What does CDN stand for?

The term CDN stands for Content Delivery Network. This refers to a system of distributed servers that work together to deliver web content, multimedia, and other resources to users based on their geographic location. The primary goal of a CDN is to enhance the performance, reliability, and speed of content delivery for web applications.

CDNs accomplish this by caching content in multiple locations around the world, which minimizes latency and load times for users accessing the content. When a user requests a resource, the CDN retrieves it from the nearest server, ensuring faster data transfer and improved user experience. Content Delivery Networks are particularly important for streaming video services, e-commerce sites, and any application requiring high availability and quick responses.

Understanding the correct definition of CDN helps to appreciate its significance in optimizing online content performance and reliability for global audiences.
