It is said about the Internet that it is a global system of interconnected networks, which connects millions of computers and thereby exchange data, information, and video. The Internet is also often referred to as ‘The Information Highway’. This means that there is a direct and comprehensive way to get internet information.
The history of the origins of the Internet is traced back to 1958 when the Department of Defense of the United States of America established the Advanced Research Projects Agency (ARPA). The purpose of this project was to connect computers in various universities and in the Defense Department of the US to develop fast in defense and technology.
In this sequence ARPANET (Advanced Research Project Administration Network) was established in 1969. With the establishment of ARPANET, it became one of the most popular media of information, data, and message sharing among research scholars, engineers, doctors, scientists, and students. People sitting away from this latest communication media also started playing various types of games and sharing their interests and hobby with each other which has become famous among us as Facebook and social networking sites.
Although ARPANET started with just a few computers, it soon connected with millions of computers and started sharing various types of information and data.
Meanwhile, in the 1980s, another American agency, the ‘National Science Foundation’, created another new high-capacity network NSFnet that was several times more quality and efficient than ARPANET. But the biggest problem with NSFnet was that it allowed only academic research work on its network. Thus the need for a powerful networking communication for private business operations was felt. This was the reason that keeping in mind the needs of businessmen and other professionals, many private companies gradually started to establish their own networks which merged with ARPANET and NSFnet over time and later took the modern form of internet.
The Internet is known by the name of the Internet as the network that gave birth to the interlinking of ARPANET and NSFnet and other private networks. ARPANET was discontinued in 1990 and the government’s financial help for NSFnet was also discontinued. But with this, the trend of commercial networking started gradually, which is working in front of us in the present form. On 15 August 1995, for the first time, Videsh Sanchar Nigam Limited (VSNL) and Internet Service Provider (ISP) started Internet service in India. It is said that the first telephone directory was made available on the internet by the state of Sikkim.
We need computers, modems, web browsers, telephone lines, and Internet Service Providers (ISPs) as devices for internet connection.
In the modern era of the Information Revolution, the Internet is being used extensively for a variety of tasks in all areas of our daily lives. This technology has incredibly changed the look of the twenty-first century. It has dramatically changed the way people around the world work together with lifestyle, science, technology, and communication. Today there will hardly be any area of human knowledge and life where computers will not be used.
