 The Invention of the Internet

Unlike technologies such as the light bulb or the telephone, the internet has ho single”invento.” Instead, it has evolved over time. The Internet got its start in the United States more than fifty year ago as a government weapon in the Cold War for year’s scientists and researchers used it to communicate and share data with one another.

The Birth of the Arpanet

Scientists and military experts were especially concerned about what might happen in the event of a soviet attack o the nation’s telephone system. Just one missile. They feared could destroy the whole network of lines and wires that made efficient long –distance communication possible. In 1962 a scientist from M.I.T. and ARPA named J.C.R.  Luckier proposed a solution to this problem: a “galactic network” of computers that could talk to one another. Such a network would enable government leader to communicate even if the soviets destroyed the telephonic system.

The Invention of the Internet

By the end of the 1970s, a computer scientist named Vinton Cerf had begun to solve this problem by developing a way for all of the computers on all of the world’s mini-networks to communicate with one another. He called his invention “Transmission Control Protocol,” or TCP. (Later, he added an additional protocol, known as “Internet Protocol.” The acronym we use to refer to these today is TCP/IP.) One writer describes Cerf’s protocol as “the ‘handshake’ that introduces distant and different computers to each other in a virtual space.”

First network equipment

On August 29, 1969, the first network switch and the first piece of network equipment called “IMP” Interface Message Processor is sent to UCLA.

On September 2, 1969, the first data moves from the UCLA host to the switch. The picture to the right is Leonard Klein rock next to the IMP.

In simple A network of network in called internet.

Development of wide – area networking

With limited exceptions the earliest computers were connected directly to terminals used by individual’s users typically in the same building or site such Web Page Networks became known as local area networks. Networking beyond this scope known as wide area networks emerged during the 1950 and became established during the 1960.

The network grows

By the end of 1969 just four computers were connected to the Arpanet but the network grew steadily during the 1970s. in 1971 it added the university of Hawaii’s aloha net and two years later it added networks ad London’s university college and the total data establishment in Norway as packet switched computer networks multiplied.
