The World Wide Web is a system of internet servers that support specially formatted documents. The web browser is a software application that runs on an Internet-connected computer that is used to make it easy access the World Wide Web. Internet users can retrive, present and transfer information interactively on the internet . Browsers are able to display web pages in different formats. The two most specialised browsers are:

Kiosk mode browsers and Line mode browsers. The kiosk mode browser are designed  easy to use by the public. They can allow limited access to a range of information, they can be operated using robust interfaces , like touch screens. The line kiosk mode browser has a different format, it is generally character-based and unable to display graphics (images, animations etc..).

HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. It is what allows Web clients and Web servers to communicate with each other. When you enter a Web address (URL) in a browser, this actually sends an HTTP command to the Web server directing it to fetch and transmit the requested Web page and display the information in your browser. All Web servers serving Web sites and pages support the HTTP protocol.

Example: The URL to reach this webpage is

http://cstudies.wordpress.com/

Once you enter the URL

http://cstudies.wordpress.com/ into the address box, the browser breaks that Web address down into three distinct parts.

1. The Protocol: “http”
2. The server name: ” cstudies.wordpress.com”
   1. The file name, which follows the server name:     ”browser.html”
