History of Internet

Internet start with a project called the ARPANET which was sponsored by the united states department of defense, an advanced research project agency (ARPA). The department of defense (DOD) thought of building a network that would work under adverse conditions. the original idea was to build a network capable of carrying military and government information during a “nuclear event”.

till the late 1970s ARPANET operated to provide a connection facility to around a dozen research sites. the internet has its roots in the U.S. military which funded a network in 1970. Later in 1982, ARPA established the Transmission control protocol (TCP) and internet protocol (IP), as the protocol suite, commonly known as TCP/IP – a connection protocol between sites, which is still in use today and is the primary method of connecting to the internet. the number of networks, Machines, and users connected to the ARPANET grew rapidly after TCP/IP became the only official protocol on Jan. 1, 1983.

as more and more computers connected, the ARPANET was replaced by NFSNET, which was funded by the national science foundation. Thanks to the National Science Foundation (NSF), USA, whose network of strategically located supercomputers, NSFNET and allowed the people to share information from home or their institutions. The other networks, which developed in parallel, like BITNET of IBM, X.25, Frame relay, based in Europe, and UUCP based in bell labs got slowly absorbed or got connected to the internet, in order to provide a unified information-sharing medium.

The network although started in the US, slowly started reaching other countries by connecting the networks of other countries.
