Internet

Internet is a global computer network - a distributed packet-switched network

The Internet is a global telecommunications system that connects millions of smaller networks. It lets people converse across distance and platforms. The Internet originated in 1969 as the Defense Department's Advanced Research Project Agency (ARPA) to allow wartime communication. Universities with defense-related initiatives received computers. When scholars went online, this network became scientific. As ARPAnet grew, the NSF took over its administration (NSF). This shift in responsibilities transformed the science-focused ARPAnet into the commercially-funded Internet utilized by millions today.

Internet transports electrical messages between networks. In most networks, a server with lots of memory and storage is the hub. The server manages information flow between networked computers, printers, and other servers. ISPs provide Internet connectivity through their servers. Many professors utilize a free university ISP. America Online, phone companies, and cable providers also provide Internet connection. Phone lines, cable modems, smartphones, and other mobile devices may access the Internet.

Snippet from Wikipedia: Internet

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a network of networks that comprises private, public, academic, business, and government networks of local to global scope, linked by electronic, wireless, and optical networking technologies. The Internet carries a vast range of information services and resources, such as the interlinked hypertext documents and applications of the World Wide Web (WWW), electronic mail, internet telephony, streaming media and file sharing.

Most traditional communication media, including telephone, radio, television, paper mail, newspapers, and print publishing, have been transformed by the Internet, giving rise to new media such as email, online music, digital newspapers, news aggregators, and audio and video streaming websites. The Internet has enabled and accelerated new forms of personal interaction through instant messaging, Internet forums, and social networking services. Online shopping has also grown to occupy a significant market across industries, enabling firms to extend brick and mortar presences to serve larger markets. Business-to-business and financial services on the Internet affect supply chains across entire industries.

The Internet has no single centralized governance in either technological implementation or policies for access and usage. Each constituent network sets its own policies. The overarching definitions of the two principal name spaces on the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN). The technical underpinning and standardization of the core protocols is an activity of the non-profit Internet Engineering Task Force (IETF).
