Many people think that the Internet is a recent innovation, when in fact the fundamental ideas behind the Internet have been around for over a quarter century. The Internet was invented by the US Department of Defence as a means of communication if they were attacked by Russia. That was in 1969. The WWW on the other hand was invented by an Englishman called Tim Berners Lee in Switzerland in 1989. The Internet dates back to the 1950s and 60s, although few people knew of it then as it was part of the American defense system.
Today, the Internet is not owned or funded by any one institution, organization, or government: it is a self-sustaining widespread information infrastructure accessible to hundreds of millions of people world-wide. The Internet is, however, directed by the Internet Society(ISOC), which is composed of volunteers. ISOC appoints the IAB(Internet Architecture Board)sub-council, the appointed members of which decide on standards, network resources, and network addresses. The day-to-day issues of Internet operation are taken care of by a volunteer group called the IETF(Internet Engineering Task Force).
In brief a small number of governing boards work to establish common standards, few rules or single organization bind the Internet, essentially the Internet is in the most part of an ungoverned global network of networks.
