History Of The Internet In 1964, the RAND proposal was put forward. Written by Paul Baran, this proposal stated the principles of a new network which was to be built for maximum strength and flexibility. This new network would have no central authority. The principles of this network were that all the nodes would be equal in status and each could send and receive messages. All the messages would be sent in packets, each with its own address. These packets would be sent at one node and would arrive at another one. This may seem rather obvious, but what was new was that the way the packets went through the net was not important. That means that if one node was destroyed, the rest of the nodes would still be able to communicate. This is of course was inefficient and rather slow, but extremely reliable. The Internet still uses this method nowadays, and there has been only one collective crash so far. The Pentagon\'s Advanced Research Projects Agency (ARPA) wanted to install an advanced network based on the principles in the US. The network was called ARPANET and consisted of four high speed computers (nodes). In 1969, the network, internet, arpanet, new, development, research, one, nsf, each, packets, nodes, kristula, first, called, tcp/ip, speed, society, protocol, principles, number, node, networks, later, hosts, history, high, dns, allowed, advanced, address, 1983, year, www, way, wanted
