History of the internet

The history of the internet begins with the following

  1. ARPANET: The US defence department created a project called Advanced Research Project Agency (ARPA) in the late 1960s, which was to work as a network that would allow scientist and military personnel to exchange information in war scenario without disruption in communications. The network was connected in a way which ensured that if one section of the network was damaged, the remaining computer on the network would still be able to communicate with each other. This network was called ARPANET. By 1984, ARPANET had more than 1,000 individual computers linked as hosts.
  2. NSFNET: In 1986, the national science foundation (NSF) connected its huge network of five supercomputer centre called NSFNET, to ARPANET. They used the technology developed for ARPANET to allow universities and schools to connect to each other. By 1987, NSFNET could no longer handle the amount of information that was being transferred. The national science foundation improved the network to allow more information to be transferred. This configuration of the complex came to be known as the internet. Most of the people accessing the internet until the late 1980s were scientist and researchers. In the early 1990s, many companies started to offer access to home users. This allows anyone with a modem and a computer to access the internet.
  3. WORLDWIDE WEB: The World Wide Web was created in the early 1990s by European organization for nuclear research. The goal of WWW was also to allow researchers to work together on projects and to make project information easily accessible. The first publicly accessible website was created in 1991. By the mid-1990s, over 30 million people had access to the internet. Reach this huge market, most big companies created their own sites on the World Wide Web or provide information about their products. Now there are a thousand companies on the web.
