One small step for man one Giant leap for computer kind.
In 1969 the Pentagon's Advanced Research Projects Agency (ARPA) created the for- runner to the to the Internet called the ARPAnet this was a network of 4 universities. It used myriad connections to link the 4-mainframe computers, they were located at the, Stanford Research Institute, the University of California at Los Angeles, the University of California at Santa Barbara, and the University of Utah. This way if one was 'taken out' then the flow of information could continue along other paths.
The previous networks need a direct wire connection between the computers, this was the first however that did not have this kind of connection. A new process called Packet switching changed the way the networks function. Packet switching is basically when a data file is broken down into small 'chunks' or packets consisting from one to 1500 charters for random transfer to their ultimate destination. This method allowed the same lines to carry many different flows of data, allowing many different people to communicate using the same line.
