Hour 1. Understanding HTML and XML > What Happens When You Surf The Web

What Happens When You Surf The Web

The standard model for the World Wide Web is the client/server model, a term that you have no doubt heard if you have kept an ear open for Web jargon. When you type an address such as http://www.SiteToGoTo.com in the address window of your browser and send it out, you are acting as a client of the computers of the Web. Your request is sent to a computer that serves as a directory assistance server. That computer translates the address into the machine-readable form of addresses used by computers connected to the Web. The request is then routed to the computer that hosts the site. If the host machine is able to do so, it acts as a server and sends the proper HTML file to the client that requested it. That HTML file is then received by the client (in this case, you) and the browser displays the page by following the instructions of the file.

Therefore, strictly speaking, you do not visit sites on the Web, they visit you. This is what makes it easy for the browser to show you the HTML code as explained in the previous tip.
