Technology Briefing 5 – The Internet and the World Wide Web I. The Internet A. How Did the Internet Get Started? The Internet got started in the 1960s when the U.S. Defense Advanced Research Projects Agency (DARPA) began to study was to interconnect networks of various kinds. The result was the Advanced Research Projects Agency Network (ARPANET), a large wide area network that linked many universities and research centers. In 1986, the U.S. National Science Foundation (NSF) initiated the development of a network called NSFNET which became a major component of the Internet. B. Packet-Switching Technology The Internet relies on packet-switching technology to deliver data and information across networks. Packet switching enables millions of users to send large and small chunks of data across the Internet concurrently. Packet switching is based on the concept of turn taking. See Figure TB5.1. C. Transmission Control Protocol/Internet Protocol TCP/IP is the common language that different networks use to communicate. TCP breaks information into small chunks called data packets and manages the transfer of those packets from computer to computer. IP defines how a data packet must be formed and to where a router must forward each packet.
