WWW is the most widely used technology on the Internet. Although Netscape's browser makes it easier for more people to use the Internet, all this would be just a dream without the invention of background WWW technology. 1990, Behnas Lee of CERN developed the World Wide Web, which uses a "Hypertext Markup Language" (HTML) to display files, so that complicated operations in the past are replaced by simple and interesting information browsing, and a mouse can lead people into the magical Internet world. Behnas as Lee is also known as the "father of the World Wide Web". His concepts such as HTRP, URL and HTML have been deeply rooted in people's hearts and become the "esperanto" of WWW on the Internet. 1994, W3C (World Wide Web Consortium, WWW Association) was established with the goal of establishing standards that all web developers can follow.
