The History of Internet

History Of Internet

Histor of Internet

  • The History of  Internet begins with the development of electronic computers along with the development of wide area networks in the United States.
  • The U.S. Department of Defence awarded contact for the development of the ARPANET project in the early 1960s.The first message was sent over the ARPANET in 1969.
  • Packet switching networks such as the NPL network, ARPANET, Merit Network, CYCLADES, and Telenet, were developed in the late 1960s and early 1970s using a variety of communications protocols.
  • The ARPANET project led to the development of protocols for internetworking, in which multiple separate networks could be joined into a network of networks.
  • The Internet protocol suite (TCP/IP) was developed in 1970s and become the standard networking protocol on the ARPANET.
  • In the early 1980s the NSF initiated the development of national supercomputing centers at several universities, and interconnected them in 1986 with the NSFNET project. This created network access to the supercomputers from research and education organizations.
  • Commercial Internet service providers(ISPs) began to emerge in the very late 1980s.The ARPANET was decommissioned in 1990.
  • Limited private connections to parts of the Internet by officially commercial entities began in sevaral American cities by late 1989 and 1990. The NSFNET was decommissioned in 1995, which removed the last restrictions on the use of the Internet for commercial traffic.
  • In the 1980s, the british computer scientist Tim Berners-Lee invented the world wide web, linking hypertext documents into an information system, accessible from any node on the network.
  • Since the mid-1990s, the Internet started to have a great impact on culture, commerce, and technology. There was a phenomenal rise in the communication by electronic mail, instant messanging,voice over Internet protocol(VoIP) telephone calls, two-way interactive video calls and the world wide web.
  • The rate of data transmission increased due to the use of fiber optic networks from 1 Gbit/s to 10 Gbit/s, or more.
  • The internet took over the global communication landscape almost instantly. It only communicated 1% of the total information in the year 1993, that increasrd to 51% by 2000, and more than 97% of the telecommunicated information by 2007.

  • The origin of Internet can be traced to a  U.S. Department of Defence (DoD) organization called Advanced Research Projects Ajency(ARPA).
  • ARPA developed a four node packet switching network called ARPANET in 1969.The network was intended to support the military research on fault tolerant computer networks.DoD wnated to ensure a reliable data transfer in the event of a nuclear war, even if parts of the network ha been destroyed.
  • As the years pass by, the ARPANET no longer remained an experimental network but its control was passed over to Defence Communication Agency(DCA).
  • The network then became available for the academic research, government employee and contractors.
  • It was not until 1986, however  that the dramatic growth of the Internet began.At this time, the National Science Foundation (NSF) which formed the National Science Foundation Network(NSFNET) Linked five of its regional super-computer centers together to provide a national high speed backbone network across the United states.
  • The world's fastest and most powerful computers were made available to a academic and scientific community.
  • In 1990, theARPANET was officially decommissioned.some of the major networks contributing to the growth of the internet are as follows :

  1. ARPANET
  2. USENET  (user's network)
  3. CSNET (computer science network)
  4. BITNET (because it's time network)
  5. NSFNET (National Science Foundation Network)
  6. WWW (World Wide Web)
  7. NREN (National research and education network)
  8. Intranet
  • It is said that the Internet is growing at a rate of 20% per month.The data speeds have gone up considerably, which makes the access even more fast.
  • The event which started as a military assistance program is now largely a private enterprise.

What is Internet.? |Definition of Internet |

What is Internet ..?

Definition of Internet

Definition of Internet :

The Internet is defined as the global information system that is logically linked together by a globally unique address space based on the Internet Protocol(IP) and is able to support communications using the Transmission control Protocol/Internet Protocol (TCP/IP) in order to provide, use or makes accessible,high level services layered on the communications and related infrastructure.

Description :

  • Internet was the next step of ARPANET and NSFNET.
  • Sometime in mid 1980s, people started thinking about the interconnection of many networks and the Internet came in to existance.
  • It started growing exponentially with all the types of existing  networks getting connected to internet. This was possible due to the use of TCP/IP reference model and TCP/IP protocol stack.
  • The internet is a globally existing network of networks consisting of a huge number of computers located in all the parts of the world.
  • Already billions of people share it and the number is increasing every day.



Definition of Internet



  • All the computers connected to the internet are part of this huge network.Networking is interconnection of computers. Generally the networking topologies used for networking are star,bus,ring,loop etc.
  • When a limited number of computers are to be interconnected, the local area network (LAN) is used.But in the internet the interconnection is achieved even via satellites.
  • The power that a computer gets due to the internet is amazing. It is now posible to send and receive the data with in a fewseconds of time from any part of the world.
