Internet

 

            The Internet was created to establish a decentralized network among U. government defense agencies and strategic command posts. The purpose of the Internet was to create a network infrastructure that would survive even if a large portion of the network were destroyed, specifically in the event of a nuclear war. It was conceived by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969 and was originally referred to as the ARPAnet. Over the years the ARPAnet expanded to include those affiliated with defense work such as academicians, researchers, and major defense contractors. .
             Between 1982 and 1987, Bob Kahn and Vint Cerf became key members of a team that created TCP/IP (Transmission Control Protocol/Internet Protocol), the common language of all Internet computers. After the TCP/IP formation, the loose collection of networks which made up the ARPAnet is seen as an "Internet" (an inter-connected system linked together in a network), and the Internet, as we know it today, was conceived.
             By 1990, the organization of the Internet's success, the ARPAnet, was decommissioned, leaving a legacy of over 300,000 hosts which constituted the vast network-of-networks called the Internet.
             The Internet Protocol is the protocol used to transport data (Web pages, E-mail messages, etc.) over the Internet. When data is transported, either sent or received, it travels in a series of packets. Each packet may take an entirely different physical route. The protocol has no desire to connect the packets of information, it is merely transporting a single packet. It's up to the TCP protocol to put the packets back in the right order which together create the entire TCP/IP language process among computers.

             If an obscure agency inside the Pentagon hadn't happened to hire an equally obscure psychologist named J. C. R. Licklider back in the fall of 1962, we wouldn't be living through an Internet revolution now "because the Internet would not exist.
