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.
