History Of Internet

                                        

                        The work on internet was started in 1960s during the cold war of Russia and America. America wanted to communicate with its Armed Forces. A network of four computers was developed at start.

     ARPANET  

                  During cold war, Russia launched Sputnik satellite and America developed a network. Its name was ARPANET. Its was developed for “advance research project agency (ARPA)” ARPA worked on a project to send information to armed forces at long distances. Different organizations and universities also involved in this research.

     Paul Baran

In 1964, Paul Baran published a paper on Distributed Communication Network. It was a theoretical idea for data transfer.

It included the following:

·         Decentralization of data storage

·         Digital Packets

·         Routes for data transfer

       Protocol

            Protocol is a collection of rules. In 1970s, NCP (network control protocol) was developed. It was the first standard protocol for data transfer.

     DARPA

              DARPA stands for “defense advanced research projects agency. It was a new name of ARPA. Now 37 computers were connected together. DARPA started work to share data not only on single network but also among different networks. Stanford Research Institute took part in this research.

     TCP\IP

             A team of Stanford research institute developed a protocol called TCP\IP. It stands for Transmission control protocol\INTERNET protocol. It was designed to share and transfer data among different networks.

     BITNET & CSNET

                        BITNET stands for “because its time network “and CSNET stands for “computer science network”. These networks were used for academic and research purposes. In these networks, IBM computers and university computers were connected together.

     World Wide Network

                               Soon the idea of INTERNET came out. Different universities and research institutes started work on a global network. In 1986, NSFNET was developed. It connected academic researched of different counties together.

      INTERNET 

                            Internet is now the largest network in the world. Millions of computers are connected together through different medium. People can share information, data. Any computer with a modem and telephone line can become a part of the INTERNET
