Before trying to make your own Web page and launch it on the Internet, first you need to know how Web pages work. The server receives the request for a page sent by your browser. The browser connects to the server through an IP Address; the IP address is obtained by translating the domain name. In return, the server sends back the requested page.
Web pages are written in HTML, Hypertext Markup Language. A markup language is a computer language that describes the layout, format and content of a page. The Web browser renders the page according to the HTML code.
In OU Campus, Web pages are created when you publish a pcf (page control file) which renders the Web page in aspx format (Active Server Page Extended file), which displays in your Web browser.
