A mere twenty years had passed since the invention of the ARPANET, but few people remembered it now.
For it had become a happy victim of its own overwhelming success.
Its users scarcely noticed, for ARPANET’s functions not only continued but steadily improved.
The use of TCP/IP standards for computer networking is now global.
By December 1969, there were four nodes on the infant network, which was named ARPANET, after its Pentagon sponsor (the Advanced Research Projects Agency).
This was an ARPANET broadcasting technique in which an identical message could be sent automatically to large numbers of network subscribers.
The ARPA’s original software for communication was known as NCP, “Network Control Protocol”, but as time passed and the technique advanced, NCP was superseded by a higher-level, more sophisticated standard known as TCP/IP.
This software converted messages into streams of packets at the source, then reassembled them back into messages at the destination.
As the ‘70 advanced, other entire networks fell into the digital embrace of this ever-growing web of computers.
Since TCP/IP was public domain, and the basic technology was decentralized and rather anarchic by its very nature, it was difficult to stop people from barging in and linking up.
