The Internet
Introduction
There is no doubt that the invention of radio and television had a great impact on the lives of most people. The full affect the next development in communications will eventually have can only be imagined. Already many people contact their friends by e-mail, do their shopping, banking and gain any information they want from the Internet.
The Internet then...1969 - 1984
The internet, which everyone calls the Net, started out in 1969 as an American military program called ARPANET (Advanced Research Projects Agency). It was designed to enable research centres to keep in touch with each other and exchange information more efficiently on a network which would withstand bomb damage. To begin with it consisted of just four computers, one at each of the universities of Utah, Los Angeles, Santa Barbara and Standford.
By 1972 the number of computers had grown to fifty. Britain did not really join in until the end of the seventies when the first academic network called Janet (Joint Academic Network) was set-up between five British universities.
At this time most of the computer networks in America and Europe had few connections to each other.
In 1984 networks began to interconnect. This was when the word 'Internet' was first used.
One major problem with creating the Internet was the need to use a standardised networking method. This is called TCP/IP (Transmission Control Protocol/Internet Protocol). Its a bit of a mouthful but you will see these initials very often so its worth knowing what they mean.
