The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), the nfrastructure to support email, and peer-to-peer networks for file sharing and telephony. The origins of the Internet date back to research commissioned by the united States government in the 1 960s to build robust, fault-tolerant communication via computer networks. [l] While this work, together with work in the united Kingdom and France, led to important precursor networks, they were not the Internet.
There is no consensus on the exact date when the modern Internet came into being, but sometime In the early to mid-1980s is considered reasonable.  From that point, the etwork experienced decades of sustained exponential growth as generations of institutional, personal, and mobile computers were connected to it. The funding of a new U. S. backbone by the National Science Foundation in the 1980s, as well as private funding for other commercial backbones, led to worldwide participation in the development of new networking technologies, and the merger of many networks. 3] Though the Internet has been widely used by academia since the 1980s, the commercialization of what was by the 1990s an International network resulted In Its popularization and incorporation Into virtually every aspect of modern human life. As of June 2012, more than 2. 4 billion people”over a third of the world’s human population”have used the services of the Internet; approximately 100 times more people than were using it in 1995.  Internet use grew rapidly in the West from the mid-1990s to early 2000s and from the late 1990s to present in the developing world.
In 1994 only 3% of American classrooms had access to the Internet while by 2002 92% dld. [61Most traditional communications media Including telephone, music, film, and television are being reshaped or redefined by the Internet, giving birth to ew services such as voice over Internet Protocol (VoIP) and Internet Protocol television (IPTV). Newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging and web feeds. The Internet has enabled and accelerated new forms of human interactions through Instant messaging, Internet forums, and social networking.
Online shopping has boomed both for major retail outlets and small artisans and traders. Business-to-business and financial services on the Internet affect supply chains across entire industries. The Internet has no centralized governance in either technological implementation or olicies for access and usage; each constituent network sets its own policies.  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 (ICANN).
The technical underpinning and standardization of the core protocols (Pv4 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. TerminologyThe Internet, referring to the pecific global system of interconnected IP networks, is a proper noun and written with an initial capital letter. In the media and common use it is often not capitalized, viz. the internet.
Some guides specify that the word should be capitalized when used as a noun, but not capitalized when used as a verb or an adjective.  The Internet is also often referred to as the Net. Historically the word internet was used, uncapitalized, as early as 1883 as a verb and adjective to refer to interconnected motions. Starting in the early 1970s the term internet was used as a shorthand form f the technical term internetwork, the result of interconnecting computer networks with special gateways or routers.
