What is the purpose of a Content Delivery Network (CDN)?

A Content Delivery Network (CDN) is designed to deliver web content quickly and efficiently. It achieves this by distributing content across multiple geographically dispersed servers. When a user requests content, the CDN serves it from the closest location to the user, which reduces latency and improves load times. This is particularly important for websites or services that experience high traffic or serve users from diverse locations. By efficiently distributing resources such as images, videos, and scripts, a CDN minimizes the distance data must travel, thus enhancing the overall performance and reliability of web content delivery.

Other functions such as enhancing database security, streamlining application development, or providing customer feedback mechanisms do not align with the primary purpose of a CDN, which is focused on optimizing the delivery of web content rather than addressing those specific needs.
