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

The primary function of a Content Delivery Network (CDN) is to host online assets globally. A CDN is a network of distributed servers that work together to provide fast delivery of internet content, which includes images, videos, web pages, and other digital assets. By caching these assets in various geographic locations, CDNs significantly reduce the distance data must travel to reach end users, enhancing load times and overall website performance. This geographical distribution allows CDNs to optimize content delivery based on user location, ensuring that individuals experience faster access to the resources they need, regardless of where they are situated globally.

The other choices refer to functions that do not align with the core purpose of a CDN. While enhancing website design, creating advertising content, and developing software applications are important aspects of the digital ecosystem, they do not encapsulate the specific role of a CDN in ensuring efficient and rapid access to content through global hosting capabilities.
