How did the Internet Start

Introduction :

Just imagine all the cities in the world having wonderful streets but no connections between them not even footpaths, it would be very critical existence for everyone. That was the way the computer would was until a few years ago. Now the computer world is rapidly increasing, over the past decades many computers have been linked together in seconds and companies, so users can exchange data over the networks. Over the past few years, the local grouping of computers called Local Area Networks have been connected together into a world wide network by the Internet. This vast electronic web has been named cyber space, which is a world where everyone connected electronically.

How did the Internet Start ?

In the 1950s, computers were enormous devices that filled entire rooms. They had a fraction of the power and processing ability, we can find in a modern PC. Many computers could only read magnetic tape or punch cards, and there was no way to network computers together.

ARPA aimed to change that. It enlisted the help of the company Bolt, Beranek and Newman (BBN) to create a computer network. The network had to connect four computers running on four different operating systems. They called the network ARPANET. It's original purpose was to link several computer sites in the country so that if one was destroyed the others would still function. It became so successful that universities, government departments and large corporations began to link to it also.

Without ARPANET, the Internet would not look or behave the way it does today, it might not even exist. Although other groups were working on ways to network computers, ARPANET established the protocols used on the Internet today. Morever, without ARPANET, it may have taken many more years before anyone tried to find ways to join regional networks together into a larger system.
