Brief History of the Internet

The work to develop a communication system was started in 1960s during the cold war between the USA and Russia. In 1957, Russia launched Sputnik, the first artificial earth satellite. In response to the launching of Sputnik, the Americans established the Advanced Research Projects Agency (ARPA) in 1958. ARPA was given the task to develop a communication system.

In 1969, ARPA established a small computer network. It was named as ARPANet. ARPANet stands for "Advanced Research Project Agency Network". ARPANet was a network of four computers.

The idea of computer networking soon became popular. During 1970s and 1980s several universities & research organizations developed their own computer networks. Similarly, many other networks for military use were developed.

In 1986, the National Science Foundation (NSF), another federal agency of USA, established a network and named as NSFNet. It was established for academic purpose. It was accessible by everyone. Later, it was expanded all over the country. A large number of networks of universities and research centers were connected to this network, so that they could share information. This large network of computer networks was named as Internet.

The Internet has grown rapidly since 1990. According to Internet society (the monitoring organization), the number of computer networks in the Internet is more than two millions. Similarly, the number of computers that connect to these networks is more than hundred million.
