The Sputnik Satellite
On October 4th, 1957, the soviet union sent the first artificial satellite into space leading to a break through in science and technology. -
Birth of the ARPAnet
ARPA scientist J.C.R Licklider proposed an idea; a interconnected network of computers that could communicate with each other if the ussr shut down telephones. -
Packet-switching
Donald Davies, a scientist at Britain's national Physical Laboratory developed a way to send information from one computer to another and called it "packet-switching". Packet-switching breaks down data into small blocks, or "packets" before sending it to it's destination. If this did not exist the ARPAnet would be just as vulnerable as telephones. -
The first message
On October 29, 1969, the ARPAnet sent its first message. It was a node to node message saying, "LOGIN". Although it was a huge break through it was not perfect as it crashed the brand new ARPAnet and the receiving side could only see the first two messages. -
The network
By the end of 1969 only 4 computers were connected to the ARPAnet but this would soon change as the network grows. -
ALOHAnet
In 1972 the computers joined Hawaii's ALOHAnet. It then added networks at London's University College and the Norwegian Seismic Array. The packet-switches multiplied but it became hard for it to become the internet. -
Transmission Control Protocol
In the mid 1970's Vinton Cerf fixed the problem by creating the Transmission Control Protocol. It was a device that was meant to get all the world's mini networks to communicate with each other. -
World Wide Web
Tim Berners-Lee introduced the World Wide Web to the world. It's an internet that was more then a way to just send files. It turned these files into a "web" that anyone on the internet could reach and get information from.
