What is the Internet?
Internet is a network of computers used worldwide by millions of users for communication purposes. It is a system of networks, websites, or web pages used daily for communication across great distances and various computer platforms.
History of Internet
Internet was first brought into use by the U.S. Department of Defense’s Advanced Research Project Agency (ARPA) in 1969 for the sole purpose of communication amongst them in case of any emergency war situation. Eventually, the scientist fraternity gradually used the ARPANet for their research work. But still, then, the internet was not in everyday use among the general public as a standard way of communication was not there. In the 1970s, Bob Kahn published his research at ARPA, which later evolved into Transmission Control Protocol (TCP) or Internet Protocol (I.P.), the two main protocols of the International Internet Protocol Suite. In 1983, the scientists officially established TCP/IP, and the birthday of the internet was on 1st January 1983. In 1986, the National Science Federation (NSF) of the U.S. set up interconnectivity among several universities of the United States. Thus, the United States made the emergence of computer architectures such as Domain Name System (DNS) and TCP/IP official. At the same time, along with the USA, Australia also started to adopt the new Internet system. In 1990 the first internet, ARPANET, was officially decommissioned. Several private connections and commercial entities came up across the United States, thus removing the restrictions on the use of the internet among the general public and for commercial purposes.
Who invented the WWW?
It was Tim Berners-Lee who invented the WWW (World Wide Web) in 1990 at his research laboratory in CERN, Switzerland. The World Wide Web was convenient because linking any information system to hypertext documents was very easy and was accessible from any node on the computer networking system. Then in the mid-1990s came the wave division multiplexing system (WDM). Along with it, the invention of fibre optic cables made a revolutionary impact on the technology of the internet world wide. With this invention, instant communication via electronic mail, instant messaging, Voice over Internet protocol (VoIP), telephone calls, and video calls were made possible at the beginning of the 21st century. In addition, fibre optic cables also helped in the increased transfer of the amounts of data at higher speeds, thus decreasing the time of communication.

Also, it can avoid ATM transactions and thus fraudulent transactions, and also ATM pins can be changed sitting at the comfort of home.
- Research – Research work done by the students for their P. H.D. benefits them because they do not need to spend time sitting in the library and finding the appropriate documents and papers for their work. After all, the internet helps them see the result instantly.
- Social Networking – Social Networking is one of the essential methods of communication in the 21st century, and without the internet and faster broadband services, it would not have been possible. Nowadays, people can find every news on social media, just one click away from every person worldwide.
- Navigation – With the advancement of the internet, navigation systems have become a part of our daily lives. After going to a new place, we use our mobile phones to find our way through the new site with the help of navigation software like Google Maps and others.
