The Internet: History and Information.

Here is the Information and History of the Internet and how did it come into existence. 

In 1963, Unit of the Advanced Research Project Agency (ARPR), founded by the United States Department of Defense, began developing a computer network. Drive out of fear of the Soviet nuclear threat, it aimed to link computers at different locations so that researchers would be able to exchange data electronically without needing fixed routes between them, making the network less vulnerable to attacks including even nuclear attacks.

Data were converted to telephone signals using the modem (modulator-demodulator), developed at AT&T in the late 1990s, key developments were made, including "packet switching"-the packaging, marking and routing data system that allows it to be transmitted over the network across devices. The system was proposed by Paul Baran (before 1926) which broke down every message without tiny chunks. This would be fired into the network, which would route to the desired destination the various bits. So, if pieces of a message were traveling through Dallas from Seattle to New York, but Dallas suddenly went offline, then the network would immediately move through Denver. Different sections or packets of a message will go through various paths, even if they arrived in the wrong order, before being resembled in the original message at their destination. In 1964 Paul Baran published his idea, and five years later the new network named ARPANET which went live.

As the nuclear war theater receded in the early 1970s, the Internet was renamed to ARPANET and effectively opened to all users. The development of e-mail, the creation of the World Wide Web (www), and browser technology have since enabled the Internet to become a rich facility for communication.
