Along with making sure your files can be seen by internet users around the world, a web server provides other important services as well. First and foremost is the ability to create email addresses based on your domain name and to send and receive email with them. The web server also has various types of software installed on it that allow your website to run programs, create and manage databases, display video, and many other functions you might find useful. Almost any type of computer can function as a web server, but it's the software that's on it that makes it a server.
