WWWpalvelimien, or web servers, are computer programs that process requests from clients, typically web browsers, and deliver web pages and other content over the internet. When a user types a web address into their browser, the browser sends a request to the designated web server. The web server then locates the requested resource, such as an HTML file or an image, and sends it back to the browser to be displayed.

Web servers are essential for the functioning of the World Wide Web. They store and manage the files that make up websites, and they are responsible for serving these files to users who access them. Common examples of web server software include Apache HTTP Server, Nginx, and Microsoft Internet Information Services (IIS). These programs are designed to handle a large number of concurrent connections and to deliver content quickly and efficiently.

The process of delivering web content involves several protocols, most notably HTTP (Hypertext Transfer Protocol) and its secure version, HTTPS. When a client requests a resource, the server responds with a status code indicating the success or failure of the request, along with the requested content. Web servers can also host dynamic content, which is generated in real-time by server-side scripts or applications, allowing for interactive and personalized web experiences. The performance and reliability of a web server are critical factors for the accessibility and user experience of any website.
