To request a webpage, you type a URL into your web browser (1). Your computer contacts its local domain name server (2), which converts the address of the server that contains the web page you want into an IP address. The name of the page you are requesting is then sent to the web server in the form of a packet.

Your request is routed (3) through the Internet to the web server.

The web server (4) sends back the requested document in packets.

The packets are reassembled by TCP/IP on your computer and the web browser interprets the html to display the page.
