The
Internet is a global system of interconnected computer networks that use the
standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.
It is a network of networks that consists of millions of private, public,
academic, business, and government networks of local to global scope that are
linked by a broad array of electronic and optical networking technologies. The
Internet carries a vast array of information resources and services, most
notably the inter-linked hypertext documents of the World Wide Web (WWW) and
the infrastructure to support electronic mail. Internet History
The origins of the Internet reach
back to the 1960s when the United States funded research projects of its
military agencies to build robust, fault-tolerant and distributed computer
networks. This research and a period of civilian funding of a new U.S. backbone
by the National Science Foundation spawned worldwide participation in the
development of new networking technologies and led to the commercialization of
an international network in the mid 1990s, and resulted in the following
popularization of countless applications in virtually every aspect of modern
human life. As of 2009, an estimated quarter of Earth's population uses the
services of the Internet.
The Internet has no centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own standards. Only the overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address space and the Domain Name System, are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols (IPv4 and IPv6) is an activity of the Internet Engineering Task Force (IETF), a non-profit organization of loosely affiliated international participants that anyone may associate with by contributing technical expertise.
