The World Wide Web or just ‘The Web’ is celebrating its 30th anniversary today since its creation back in 1989. For those who do not know much about it, this article is aimed to bring you up to speed.

English scientist Tim Berners-Lee invented the World Wide Web in 1989. He wrote the first web browser in 1990 while employed at CERN near Geneva, Switzerland. The browser was released outside CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991. The World Wide Web has been central to the development of the Information Age and is the primary tool billions of people use to interact on the Internet.

The browser is an application that helps one access the information stored in the World Wide Web via the Internet.

Web resources may be any type of downloadable media, but web pages are hypertext media which have been formatted in Hypertext Markup Language(HTML). Such formatting allows for embedded hyperlinks which contain URLs and permit users to easily navigate to other web resources. In addition to text, web pages may contain other media content and software components that are rendered into the user’s web browser as consistent pages of multimedia content.

Multiple web resources with a common theme, a common domain name, or both, make up a website. Websites are stored in computers which are running a program called a web server which responds to requests made over the Internet from web browsers running on user’s computers. Website content can be largely provided by a publisher, or interactively where users contribute content or the content depends upon the users or their actions. Websites may be provided for myriad informative, entertainment, commercial, governmental, or non-governmental reasons.

The terms Internet and World Wide Web is often used without much distinction. However, the two do not mean the same thing. The Internet is a global system of interconnected computer networks. In contrast, the World Wide Web is a global collection of documents and other resources, linked by hyperlinks and URIs. Web resources are accessed using HTTP or HTTPS, which are application-level Internet protocols that use the Internet’s transport protocols.
