What is a Content Delivery Network (CDN) primarily used for?

A Content Delivery Network (CDN) is primarily utilized for distributing web content efficiently. The main function of a CDN is to improve the delivery speed and accessibility of content by storing cached versions of data in multiple geographic locations. This distribution allows users to access content from a server that is physically closer to them, reducing latency and enhancing load times.

When static files such as images, stylesheets, or scripts are accessed from a CDN, they can be delivered more quickly than if they were retrieved from a single, centralized server. This is especially beneficial for websites that experience high traffic or serve users across different regions, as it helps to ensure that the content is consistently available and performs well regardless of the user's location.

In contrast, other options mention aspects like cost reduction or secure data storage, which do not directly relate to the primary function of a CDN. While a CDN can lead to cost savings on bandwidth and reduce server loads, its essential purpose is about efficient content distribution rather than hosting or data security. Creating interactive website elements pertains to the functionality and design of a website rather than the infrastructure for delivering content.
