In this article we will discuss Hypertext Transfer Protocol and Hypertext Markup Language, will make brief discussion on Hypertext Transfer Protocol and Hypertext Markup Language, In last article we discuss about Common P2P Applications.
When a web address or uniform resource locator (URL) is typed into a web browser, the web browser establishes a connection to the web service running on the server using the HTTP protocol.
URLs and Uniform Resource Identifier (URIs) are the names most people associate with web addresses. Short for Hyper Text Markup Language, the authoring language used to create documents on the World Wide Web. HTML is similar to SGML, although it is not a strict subset. HTML defines the structure and layout of a Web document by using a variety of tags and attributes.
To better understand how the web browser and web server interact, we can examine how a web page is opened in a browser. For this example, use the http://www.google.com/index.html URL.
The browser interprets the three parts of the URL:
1. http (the protocol or scheme)
2. www.google.com (the server name)
3. index.html (the specific filename requested)
The browser then checks with a name server to convert www.cisco.com into a numeric IP address, which it uses to connect to the server. Using HTTP requirements, the browser sends a GET request to the server and asks for the index.html file. The server, sends the HTML code for this web page to the browser. Finally, the browser deciphers the HTML code and formats the page for the browser window.
