The ancestry of the Internet is considered to be the ARPA – Advanced Research Projects Agency. That division of Do D put forward the idea of creating a network, or web which is different from what we call the Internet today though. Later on under the name of DARPA – Defense Advanced Research Projects Agency – this division faced the problems of local and global crucial information exchange by using protocols. Under request of the Department of Defense and it is financial support the first intranet work – Arpanet – began its development. In 1969, December, four major junction points – UCLA, Stanford Research Institute, the University of Santa-Barbara and the University of Utah – were integrated into a common network. In order to appropriately exchange the pieces of information all of them agreed on introducing a common to everyone protocol. In a year there were up to fifteen junction points which share the information by means of that common protocol, namely NCP, or Network Control Protocol. The reason of ARPA net's research activity was in fluent exchange of information between university scientific centers and Headquarter of the Department of Defense. Mainly that type of information was of defensive nature and addressed to use the resources of existing supercomputers at their full, powerful enough to process several flows of loaded streams of information. Our family is closely connected with Internet – we use online Travelocity Coupons each time when we want to book tickets or rent a car or a hotel. That way ARPA net reduced dramatically the efforts of intercommunication of centers located all over the USA and brings it to a certain centralized location. Further development of the network was consigned under responsibility of DCA, or the Defense Communications Agency, which simultaneously developed the project on introducing the protocol necessary for better intercommunication between the local networks. That protocol is still widely used in modern Internet and is called TCP/IP, which stands for Transmission Control Protocol/Internet Protocol. Such promising prospects attracted many research workers, scientists in technologies and simply enthusiastic people. DARPA organized a great many non-official meetings in order to bring all the groups together and share the ideas on the project realization. Since 1979 into the project devoted to the TCP/IP entered a huge amount of different groups on technologies so that DARPA formed an informal committee for coordination and management of the protocol, developing experimental research, constructing platforms and architectures to operate on and many other future considerations on future web introduction. That committee was later called the ICCB, or Internet Configuration and Control Board, and gathered annually up to the year 1983, during which it was reorganized and renamed as the Internet Activity Board.
It was in 1983 when the TCP/IP protocol officially recognized as the military standard of the USA, and since then every host connected to the ARPA net had to operate only under that protocol in order to interconnect within the network. Simultaneously, the term “Internet” was suggested as an appropriate structure since the original ARPA net was split into two branches by that time, namely MIL net – insecure Defense Data Network, and a newer ARPA net. And the term Internet was referred to both of these branches. Nowadays we can consider that the ARPA net was a true ancestry of modern Internet as we know it, and this is the way why the IT related personnel always refer to origins of the ARPA net rather than MIL net in order to troubleshoot the network and get rid of certain bottlenecks.
