Also known as the Web or WWW, it is the user-friendly information system on which users interact with others and resources on the Internet, which forms the framework for the Web and undergirds the Web’s technological power. Invented in 1989 by the English scientist Tim Berners-Lee, the Web was available for public use in 1991. As websites were constructed, the Web gained popularity and now in 2021 serves as the platform for 4.66 billion people for its resources and interaction.

The World Wide Web (abbreviated as WWW or W3, commonly known as the web), is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks.

The terms Internet and World Wide Web are often used in every-day speech without much distinction (as can be seen in the several subcategories below, titled "Internet ..." that should be "World Wide Web ..."). However, the Internet and the World Wide Web are not one and the same. The Internet is a global data communications system. It is a hardware and software infrastructure that provides connectivity between computers. Simply, "Internet is a network of networks", where two or more than two computers connected through the wired or wireless network for sending and receiving the date like- mails, video, song etc. In contrast, the Web is one of the services communicated via the Internet. The Web is a collection of interconnected documents and other resources, linked by hyperlinks and URLs. Other services using the internet include electronic mail, File Transfer Protocol, Telnet, online chat, Voice over Internet Protocol, Instant messaging, Fax, and Usenet.

This protocol is the HyperText Transfer Protocol (HTTP)

5 Browsers A turning point for the World Wide Web began with the introduction of the Mosaic web browser in 1993, a graphical browser developed by a team at the National Center for Supercomputing Applications at the University of Illinois at Urbana- Champaign. A turning point for the World Wide Web began with the introduction of the Mosaic web browser in 1993, a graphical browser developed by a team at the National Center for Supercomputing Applications at the University of Illinois at Urbana- Champaign. This allowed the distribution of images and the standard text-only format from previous browsers. This allowed the distribution of images and the standard text-only format from previous browsers.
