The history of internet:
On the fourth of October in 1957 an event occured that world change the world. The Soviet Union successfully launched the first satellite into Earth’s orbit. Called Sputnik 1
, it shocked the world—especially the United States of America, who had their own programme of satellite launches underway, but had yet to launch.
This event lead directly to the creation of the US Department of Defence ARPA (the Advanced Research Projects Agency), due to a recognised need for an organisation that could research and develop advanced ideas and technology beyond the currently identified needs. Perhaps their most famous project (certainly the most widely used) was the creation of the Internet.
In 1960, psychologist and computer scientist Joseph Licklider published a paper entitled Man-Computer Symbiosis
, which articulated the idea of networked computers providing advanced information storage and retrieval. In 1962, whilst working for ARPA as the head of the information processing office, he formed a group to further computer research, but left the group before any actual work was done on the idea.
The plan for this computer network (to be called ARPANET
) was presented in October 1967, and in December 1969 the first four-computer network was up and running. The core problem in creating a network was how to connect separate physical networks without tying up network resources for constant links. The technique that solved this problem is known as packet switching and it involves data requests being split into small chunks (packets
,) which can be processed quickly without blocking communication from other parties—this principle is still used to run the Internet today.
This concept received wider adoption, with several other networks springing up using the same packet switching technique—for example, X.25 (developed by the International Telecommunication Union) formed the basis of the first UK university network JANET (allowing UK universities to send and receive files and emails) and the American public network CompuServe (a commercial enterprise allowing small companies and individuals access to time-shared computer resources, and then later Internet access.) These networks, despite having many connections, were more private networks than the Internet of today.
This proliferation of different networking protocols soon became a problem, when trying to get all the separate networks to communicate. There was a solution in sight however—Robert Kahn, whilst working on a satellite packet network project for ARPA, started defining some rules for a more open networking architecture to replace the current protocol used in ARPANET. Later joined by Vinton Cerf from Stanford University, the two created a system that masked the differences between networking protocols using a new standard. In the publication of the draft specification in December 1974, this was called the Internet Transmission Control Program
.
This specification reduced the role of the network and moved the responsibility of maintaining transmission integrity to the host computer. The end result of this was that it became possible to easily join almost all networks together. ARPA funded development of the software, and in 1977 a successful demonstration of three different networks communicating was conducted. By 1981, the specification was finalised, published and adopted; and in 1982 the ARPANET connections outside of the US were converted to use the new TCP/IP
protocol. The Internet as we know it had arrived.
