World Wide Web (WWW)

World Wide Web or Web was invented by Sir Tim Berners-Lee in 1989. Short for World Wide Web, the WWW, W3, or web is a graphical interface for the Internet that was first introduced to the public on August 6, 1991, by Tim Berners-Lee. A few days later on August 23, 1991, it was available to everyone.

The World Wide Web, commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators, which may be interlinked by hypertext, and are accessible over the Internet. The resources of the WWW may be accessed by users by a software application called a web browser.

Web consists of three key components:

HTML – Hypertext Markup Language. This is a standard markup language used to create web pages.
URL – Uniform Resource Locator. This is the understandable form of a web address which is used to identify a resource.
HTTP – Hyper Text Transfer Protocol. This protocol is stateless and acts as the foundation of the Web.
