What is a World Wide web

The World Wide Web (www, W3) is an information space where documents and other web resources are identified by URLs, interlinked by hypertext links, and can be accessed via the Internet.[1] It has become known simply as the Web. The World Wide Web was central to the development of the Information Age and is the primary tool billions use to interact on the Internet, and it has changed people's lives immeasurably. The World Wide Web is falsely believed to be synonymous with the Internet by the general public because it has been by far the most popular application for most of the period since home Internet use became widely available in 1994. The Internet itself is the worldwide "network of networks" connected by the TCP/IP protocols while the Web is the universe of documents designated with URLs that exists on discrete Internet hosts and is connected by hyperlinks that can be accessed with browsers. A URL can be stored on a local disk or in an intra-web, but usually it uses the Domain Name System to address information on the global Internet. The World Wide Web was invented by English scientist Tim Berners-Lee in the late 1980s and the first blueprint for the system was published in March 1989. He completed the first web browser and site in December 1990 while employed at CERN in Switzerland Web pages are primarily text documents formatted and annotated with Hypertext Markup Language (HTML). In addition to formatted text, web pages may contain images, video, and software components that are rendered in the user's web browser as coherent pages of multimedia content. Embedded hyperlinks permit users to navigate between web pages. Multiple web pages with a common theme, a common domain name, or both, may be called a website. Website content can largely be provided by the publisher or interactive where users contribute content or the content depends upon the user or their actions. Websites may be mostly informative, primarily for entertainment, or largely for commercial purposes.
