What Is Internet
The Internet simply “the Net,” is a worldwide system of computer networks .Internet is a network of networks. In internet network users at any one computer can connect with other computer, if they have permission, get information from any other computer.
The Main idea of ARPA credited as being Leonard Kleinrock‘s . He published his first paper entitled “Information Flow in Large Communication Nets” on May 31, 1961.What is internet-Tectrick.org
At 1962, J.C.R. Licklider become the first Director of IPTO. He give his vision of a galactic network. After addition to ideas of Licklider and Kleinrock, Robert Taylor helped create the idea of the network that later became ARPANET ,today’s Internet.Internet was developed by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1969 .Internet first name was ARPANet.
The cause to create of internet was to create a network which would allow users to connect a research computer of one university to “talk to” research computers of other universities.
A benefit of ARPANet’s design was that. because messages could be routed or rerouted in more than one direction. This network could continuously in function ,even if parts of internet were destroyed in the event of a military attack or other disaster.
The ARPANET was very successful widely. Every university in the country wanted to sign up. This success mean,the ARPANET(Internet) began getting difficult to manage. Because, with the large and growing number of university sites on it. It was broken into two parts:
- MILNET. In this network military site are oprerated.
- And a smaller ARPANET for the nonmilitary sites.
These two networks remained connected. A technical scheme called IP (Internet Protocol).This Internet Protocol enabled traffic to be routed from one network to other as necessary.All the networks that are connected in the Internet known with name IP. They all can exchange messages.
It started with just two networks.IP was designed to allow for thousands of networks. An fact about the IP design is that every computer on an IP network is, in principle, just as capable as any other, so any machine can communicate with any other machine.
