Basics of the Internet

 

The Internet began in 1969, which was used by the U. S. Defense Department. A four computer network called ARPAnet was designed by them so that research scientists could communicate each other via computer.


ARPAnet grew to about two dozen sites in approximately within two years and by 1981, consisted of more than two hundred sites. In 1991, ARPAnet was officially disbanded and the network, which now consisted of hundreds of sites, came to be known as the Internet.



When Internet Technology came to notice, commercial organizations began to recognize the use of such a network which converted the whole world into a “Global village”. Internet allowed almost instant access to business or commerce data and a host of other services such as E-Mail and E-Commerce.


The rapid growth of the Internet was happened  due to participation of some networking companies like British Telecom, Hyundai, AT&T and others. They were setting up fast and reliable networks that encircled the globe as they were taking the role of step the network, maintain it, monitor it and expand the existing networks.


 When Internet Technology growing rapidly, hence the ISP (Internet Service Providers) came to existence. So the network providers gave access to the internet via ‘Gateways’. Using ISP gateways it is perfectly possible to route data from one point of network to another.


ISP’s in turn offer clients access to the internet via gateways as paid for service. An ISP’s gateway generally consists of a server with a permanent connection to the internet. The server’s connection to the internet is called its ‘Pipeline’. Special hardware is used for pipeline connection. ISP pipeline bandwidths of 2GB to 10GB are quite common.
