How do websites work?
Websites are composed of a group of files that are stored on a web-server, a computer on the Internet that serves up data when you request it.
In their most basic form, they are composed of files with a mixture of HTML (HyperText Markup Language) instructions and the text that is to be displayed. Once a request is received and processed by the web-server, a copy of the file is sent to your computer's browser, where it's interpreted and becomes a web page.
