Hi,
We are well known of using http on the address bar with URL(Unified Resource Locator) to get response from the server.

Here some more useful information

(HyperText Transfer Protocol) The communications protocol used to connect to servers on the Web. Its primary function is to establish a connection with a Web server and transmit HTML pages to the client browser or any other files required by an HTTP application. Addresses of Web sites begin with an http:// prefix; however, Web browsers typically default to the HTTP protocol. For example, typing Yahoo! is the same as typing Yahoo!.

HTTP is a "stateless" request/response system. The connection is maintained between client and server only for the immediate request, and the connection is closed. After the HTTP client establishes a TCP connection with the server and sends it a request command, the server sends back its response and closes the connection (see cookie).

Version 1.0 of HTTP caused considerable overhead to a Web download. Each time a graphic on the same page or another page on the same site was requested, a new protocol connection was established between the browser and the server. In HTTP Version 1.1, a persistent connection allowed multiple downloads with less overhead. It also improved caching and made it easier to create virtual hosts (multiple Web sites on the same server). See HTTP-NG and HTTP header.

Web browsers communicate with Web servers via the TCP/IP protocol. The browser sends HTTP requests to the server, which responds by sending back headers (messages) and files (HTML pages, Java applets, etc.). See HTTP header.

And i have attached the web server fundamentals for our reference
