What is Internet ?


We often keep saying or listening this word “Internet” , but do we aware what is it actually ? Lets learn about this technology?

Its no exaggeration to say that it has changed our lives in many ways which we had not ever imagined. In late 1960s it has evolved as concept in collaboration with universities , government and industries. Today, on internet we can work from home, meet anyone and discuss, buy groceries , conduct business meeting and many more.

The internet is a globally connected network system that uses TCP/IP to transmit data through various types of media.

It is based on few concepts, the first is packet switching which involves routing the data in specially formatted units from source to destination using network switches and routers.

Open architecture networking is enabling different providers to use any individual network topology they want, and the networks still work together. Transmission control protocol/Internet Protocol (TCP/IP) is making open architecture networking possible. Protocol is basically set of rules under which any process works. TCP assembles a message or file into smaller packets that are transmitted over the network and IP reads the address part of each packet so that is gets to the right destination.

Internet Protocol (IP): The internet’s primary component and communications backbone. Because it is comprised of hardware and software layers, the IP communication standard is used to address schemes and identify unique connected devices. Prominent IP versions used for communications include IP version 4 (IPv4) and Internet Protocol version 6 (IPv6).

The internet is the most cost-effective communications method in the world, in which the following services are instantly available:

  • Email
  • Web-enabled audio/video conferencing services
  • Online movies and gaming
  • Data transfer/file-sharing, often through File Transfer Protocol (FTP)
  • Instant messaging
  • Financial services
  • Internet forums
  • Social networking
  • Online shopping
  • WWW

The inter-net originated with the U.S. government, which began building a computer network in the 1960s known as ARPANET. In 1985, the U.S. National Science Foundation (NSF) commissioned the development of a university network backbone called NSFNET. The system was replaced by new networks operated by commercial inter-net service providers in 1995. The internet was brought to the public on a larger scale at around this time.
