As we have already discussed the importance of the web protocols in our previous article. In this where we are going to talk about Hypertext Transfer Protocol (HTTP).

HTTP is a protocol used to transfer Web pages from a Web server to a Web client. The Web client is usually a Web browser.

Specifically, HTTP is the set of rules required to exchange files, such as text,  images, video and multimedia content, across the Web.

An essential concept of HTTP is that files contain references to other files, so they are “linked” to one another. The files transferred by HTTP are HTML files and others that HTTP can serve. Web servers are often called HTTP servers.


Hypertext Transfer Protocol uses the Port no: 80.

According to Wikipedia,

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text.

It was actually introduced in 1990 to 1991 but the development of HTTP was initiated by Tim Berners-Lee at CERN in 1989.
