Concept of Internet
Internet is sometimes called net. Internet is a worldwide system of computer networks. It is a network of networks. Internet is a public, cooperative and self sustaining facility accessible to hundreds of millions of people worldwide for many internet users electronic mail (e-mail) has practically replaced the postal service. E-mail is the most widely used application on net. Moreover using internet you can carry online conversations with other computers users.
The internet is simple term is a network of interlinked computers worldwide, that is accessible to all. These interconnected computers work by transmitting data through a special type of packet switching which is known as IP or internet protocol.
They provide a common language for the computers attached to the physical network. In this way all the computers conform to a standard set of rules, also called as protocols.
Internet is such a gigantic network of several different interlinked networks relating to the business, government, academic, and even smaller domestic networks, therefore internet is known as the network of all the other networks. These networks enable the internet to be used for various important functions which include the several means of communications like the file transfer, the online chat and even the sharing of the documents and websites on WWW, or the World Wide Web.
History of internet
The first recorded description of social interactions that could be enabled through networking was written by JCR Licklider of MIT in August, 1962 discussing his network concept. He envisioned a globally set of interconnected computers through which everyone could quickly access data. Licklider was the first head of the computer research program at DARPA (Defense Advanced Research Projects Agency) in October, 1962. After much work, the first two nodes of what become ARPANET on October 29, 1969.
Although ARPANET started in a small way, connecting three computes in California and one in Utah.
Computers were adding quickly to ARPANET during the following years and worked on functionally complete host to host protocol and other network software.
In October, 1972, a successful demonstration of the ARPANET was organized at the International Computer Communication Conference (ICCC). This was the first public demonstration of this new network technology to the public. In 1972, electronic-mail was introduced. Since then e-mail took off as largest network application.
In the early 1980s, the ARPANET grew into an early internet, a group of interlinked networks connecting many educational and research sites, funded by the National Science Foundation, along with original military ones. By 1990 it was clear that the internet was here to stay and DARPA and NSF bowed out in favour of the commercially run networks that comprise today’s internet.
The original ARPANET grew into the internet. It was based on the idea that there would be multiple independent networks.
