The World Wide Web (WWW), commonly known as the web, is a global collection of websites and web pages stored on servers and interconnected through hyperlinks. It is an information system that enables content sharing over the Internet through user-friendly ways meant to appeal to users beyond IT specialists and hobbyists. The WWW consists of multiple components that enable users to access various resources, documents, and web pages on the internet. Some key features of the WWW include:
-
Web pages: These are the primary building blocks of the WWW and are linked through hyperlinks, which provide access from one specific spot in a hypertext or hypermedia document to another spot within that document or a different one.
-
Web browsers: These are applications used to access web pages by fetching the requested page, interpreting and rendering the source code, and displaying it on the users screen.
-
Hypertext Markup Language (HTML): This is a markup language used to create web pages.
-
Hypertext Transfer Protocol (HTTP): This is a protocol used to transfer data over the web.
-
Uniform Resource Locator (URL): This is a unique string that references the global address of web pages on the Internet.
The web was invented in 1989 by Tim Berners-Lee, who at the time was working at CERN. The aim was to facilitate communication between scientists worldwide by enabling the exchange of data and results of experiments and studies. The WWW is not the same as the Internet, but it is a platform that enables the retrieval or exchange of information over the Internet through HTTP.
