Internet HTTP Protocol

All communication on the web takes places through the transfer of what is known as Hypertext Transfer Protocol or HTTP. A client, like your web browser, sends a request to a server which, in turn, responds to the request. The HTTP request travels via the Internet where it is routed to a Web server associated with the domain name (such as www.google.com) in the request. The Web server receives the request and responds with a file of a special format that is sent back to the client.
