How The Internet Got StartedSome thirty years ago , the Rand stomach , Americas formost coldwar think tank, faced a strange straegic problem. How could the US authrietiessuccesfully communicate after a nuclear war?Postnuclear America would motive a comand-and-control interlocking, linked fromcity to city , state to state, institute to base . But no matter how throughly that entanglement was ar mored or protect , its switches and wiring would always bevulnerable to the impact of atomic bombs. A nuclear attack would reduce anyconceivable network to tatters. And how would the network itself be commandedand controlled ? Any central authority, any network central citadel, would bean obvious and immediate target for man enemy missle. The center of the networkwould be the very first place to go.RAND mulled over this grim stay put in deep military secrecy, and arrivedat a daring issue made in 1964.The principles were simple . The networkitself would be assumed to be unreliable at all judgment of convictions . It would be designedfrom the outgrowth to tyransc cease its all times . It would be designed from theget-go to transcend its testify unrreliability. All the nodes from computing devices inthe network would be equal in spatial relation to all other nodes , each node with itsown authority to stand up , pass , and recieve messages. The messages would bedivided into computer softwares, each packet seperatly addressed. separately packet would beginat some specified source node , and end at some other specified destination node. Each packet would wind its way through the network on an unmarriedbasis.In fall 1969, the first such node was insalled in UCLA. By declination 1969,there were 4 nodes on the infant network, which was named arpanet, after itsPentagon sponsor.The four computers could until now be programed remotely from the other nodes.thanks to ARPANET scientists and researchers could share one anothers computerfacilities by long -distance . Th is was a very handy service , for computer-time was precious in the early 70s. In 1971 ther were fifteen nodes inArpanet by 1972, thirty-seven nodes. And it was good.As early as 1977, transmission control protocol/IP was be used by other networks to link toARPANET. ARPANET itself remained fairly tightly controlled,at least(prenominal) until1983,when its military segment broke off and became MILNET. TCP/IP became morecommon,entire other networks fell into the digital embrace of the Internet,andmessily adhered. Since the software called TCP/IP was public domain and hebasic technology was decentralize and rather anarchic by its very nature,it asdifficult to obstruction people from barging in linking up somewhere or other.
