Web is made up of many blocks and there are certain standards of communication upon the web is built . These standards sit at a layer above operating systems, computer languages and internet transmissions protocols, and provide a basic medium for communication. WEB is not similar with the internet, actually the web and the Internet are two different things. Web is an application of the Internet. The two most important standards (protocols) used are

1. HTTP

2. HTML

These two protocols are used to communicate using Internet.

HTTP- It is a protocol that is defined in several RFC's(Request for comments). It is a

language spoken between our web browser(client software) and a web server(server software) so that they communicate with each other and exchange files. In order to communicate with the server, getting user input, processing that input and returning a dynamic response HTTP provides two ways to send information to a web server above and beyond the URL of a requested file.

The two ways are:

1. GET method:- HTTP/0.9 was the definition of the GET method that was used by a web browser to request a specific document.

2. POST method:- This method allows Web Browsers to send unlimited amount of data to a web server after the request headers as the message body.

HTML - Full form is Hyper Test Markup Language.

It is a very simple language used to describe the logical structure of a document. It is a simple language used to define a logical structure rather than compute anything like in other programming languages. The HTML's beauty is that it is generic enough that it can be read and interpreted by a web browser running on any machine or operating system.

But these are all done by user and server software....the user never needs to deal with the protocols itself. The browser does all the work of preparing the POST requests headers and body.
