What is the main function of a web server?

The main function of a web server is to deliver requested webpages. When a user types a URL into a web browser, the browser sends a request to the web server to retrieve the corresponding webpage. The web server processes this request, locates the requested HTML file and other associated resources (like CSS, JavaScript, and images), and sends them back to the browser for display.

This process is fundamental to how the World Wide Web operates, as web servers are designed specifically to handle HTTP requests and serve content. The efficiency and speed with which a web server can deliver these resources directly impact user experience, making this role essential in web hosting and internet infrastructure.

While the other options mention functions related to technology, they do not accurately describe the primary role of a web server in the context of serving and delivering web content to users.
