What do you need to have your website?

Any website needs an HTTP Server, this conforms to the Hyper Text Transfer Protocol. An HTTP Server is a program, it runs on a computer. The phpfox script also needs a database. A database is a group of files and a program that administers these files. A database needs a Database Server, which is also a program. Both the HTTP Server and the Database Server can run in the same computer, or they can run in different computers and still serve one website, just like they can serve many websites. Adding on, the phpfox script allows you to send emails to your users, so you also need a Mail Server which -you guessed it right- is also a program and can also run in the same computer as the others or separately. So in a nut, a Server is also a computer, a special one but a computer nonetheless.
