A Brief History Of The Internet :: essays research papers

A Brief History of the InternetWithin our clubhouse there has been a revolution, one that rivals that of the Industrial Revolution. The Technological Revolution. At the moderate of this revolution is the Internet. A place full of information, adventure, and even for roughly, romance. In our ships company today everyone has hear of this technological wonder, and many use it on a daily basis, tho for some the question still remains What is the Internet, and where did it add together from?Some 30 years ago, the RAND Corporation, the Statesns foremost nippy War think-tank, face a strange strategic problem. How could the US politics successfully tell after a atomic war? put up nuclear America would need a command-and-control intercommunicate, linked from city to city, state-to-state, and base-to-base. scarcely no subject field how thoroughly that lucre was armored or protected, its switches and fit would al managements be vulnerable to the impact of atomic bombs. A nucl ear attack would cut any conceivable network to tatters. And how would the network itself be commanded and controlled? Any key role, any network underlying citadel, would be an explicit and immediate sucker for an enemy missile. RAND mulled over this grim puzzle in deep military secrecy, and arrived at a daring solution. The network would contain no central authority. Furthermore, it would be designed from the buzz offning to operate go in tatters.The principles were simple, the network itself would be assumed to be unreliable at alone propagation (Krol 11). It would be designed from the get-go to transc break off its profess unreliability. All the pommels (computers hooked to the network) in the network would be equal in status to all other nodes, each node with its own authority to originate, pass, and receive messages. The messages themselves would be divided into packets, each packet separately addressed. each packet would begin at some specified source node, and end at some other specified destination node, winding its way through the network on an individual basis (Krol 11). The particular itinerary that the packet took would be unimportant. Only final results would count. Basically, the packet would be tossed want a intense potato from node to node, more or less(prenominal) in the stress of its destination, until it ended up in the proper place. If tremendous pieces of the network had been pursy away, that simply wouldnt matter the packets would still confront air born, lateralled wildly across the network by whatever node happened to survive.A Brief History Of The Internet essays research papers A Brief History of the InternetWithin our society there has been a revolution, one that rivals that of the Industrial Revolution.

In our society today everyone has heard of this technological w onder, and many use it on a daily basis, but for some the question still remains What is the Internet, and where did it come from?Some thirty years ago, the RAND Corporation, Americans foremost Cold War think-tank, faced a strange strategic problem. How could the US authorities successfully communicate after a nuclear war? Post nuclear America would need a command-and-control network, linked from city to city, state-to-state, and base-to-base. But no matter how thoroughly that network was armored or protected, its switches and wiring would always be vulnerable to the impact of atomic bombs. A nuclear attack would reduce any conceivable network to tatters. And how would the network itself be commanded and controlled? Any central authority, any network central citadel, would be an obvious and immediate target for an enemy missile. RAND mulled over this grim puzzle in deep military secrecy, and arrived at a daring solution. The network would have no central authority. Furthermore, it w ould be designed from the beginning to operate while in tatters.The principles were simple, the network itself would be assumed to be unreliable at all times (Krol 11). It would be designed from the get-go to transcend its own unreliability.

The particular route that the packet took would be unimportant. Only final results would count. Basically, the packet would be tossed like a hot potato from node to node, more or less in the direction of its destination, until it ended up in the proper place. If big pieces of the network had been blown away , that simply wouldnt matter the packets would still stay air born, lateralled wildly across the network by whatever node happened to survive.
