History of the Internet: The Internet has revolutionised the world as we know it today. Evey facit of our lives has been touched by this relatively new means of communication or is it as new as we may think.
How did the Internet develop: |
Leonard Klienrock |
The theory and foresight into the Internet was dreamt up way back in the early sixties when Leonard Kleinrock published the first paper on packet switching theory. Packet switching means that each message would be divided into packets each packet would be sent individually and join up once the address was reached. But it wasn't until later that the theory behind this revolutionary idea was put into pratice. ARPA ( Advanced Research Agency ) commissioned by the US department of defence set out to design a common way of connecting to any computer, and its inital purpose was to link military and research computer systems in a fail safe network it was hoped to link a network of computers in different geographical locations that would not be disabled should a nuclear attack happen,in 1969 work started on constructing a single network that was intended to connect universities and research institutions. ARPAnets first four nodes (computers) were linked using cables that ran at 50 kilobits per second. At first ARPAnet was just one network that connected lots of computers but it wasn't until 1974 that Vincent Cerf and Bob Kahn found a way "protocol" to connect various networks of which ARPANET was one to link together and enable each network to swop data.

They called this "transmission control Protocol" but it was refined to TCP/IP which Made seperate jobs of delivering data to the correct part of the net.These protocols tell computers how to locate and exchange data with one another The Internet basic protocols remain mainly unchanged today. |
