A Brief History of the Internet

The way to communicate before the Internet was the telegraph, which was invented in 1840 and was really very useful at the time.

The true origin of the Internet is in 1958... seriously... back then the USA founded the Advanced Research Projects Agency (ARPA) through its Ministry of Defense.

The objective?

Find a way to have direct communication between two computers to be able to communicate to different research bases. Only that? ... of course not, in fact it was created during the Cold War and they intended to make military communications less vulnerable by eliminating dependence on a central computer.

To do this they needed about 200 scientists and a lot of money. In 1962 ARPA created a research program under the direction of John Licklider and in 1967 ARPANET (Advanced Research Projects Agency Network) was born, a computer network that compiled the best ideas from three teams: MIT, Natinonal Physics Laboratory (UK) and the Rand Corporation, however in 1969 the first 4 computers were connected through Leonard Kleinrock's Interface Message Processor, in that same year the 'internet' opened to the public.

In 1971 ARPANET already had 23 connected points and the first email was sent by Ray Tomlinson. The following year it was presented at the First International Conference on Computers and Communication in Washington DC, where scientists demonstrated that the system did work by creating a network of 40 connected points in different places.

Between 1974 and 1982, quite a few networks were created, but the following stood out:

Telenet (1974) commercial version of ARPANET
Usenet (1979) Open system focused on e-mail that continues to function!
Bitnet (1981) linked American universities using IBM systems
Eunet (1982) which linked the United Kingdom, Scandinavia and The Netherlands.

Finally in 1981, ARPANET adopted the TCP/IP protocol and at that time the Internet (International Net) was created.

The use of the network was limited to the exchange of emails and as a documentary fund to store global information. But locating and identifying information still remains a fairly complex task. Fun fact Google in 2014 mentioned its search engine only reflected 0.004% of all information.

After that HTML was created, but you can read about this on another article here.

The Internet, the World Wide Web (www), was introduced in 1991. Two years later CERN opened the web for commercial use.
