1.Internet Is The Computer-Based Global Information System.
1.Internet is the computer-based global information system. The Internet is composed of many interconnected computer networks. Each network may link tens, hundreds, or even thousands of computers, enabling them to share information with one another. The Internet has made it possible for people all over the world to effectively and inexpensively communicate with one another. Unlike traditional broadcasting media, such as radio and television, the Internet does not have a centralized distribution system.
HISTORY
Some thirty years ago, the AMERICAN RAND Corporation faced a strange strategic problem. How could the US authorities successfully communicate after a nuclear war? Postnuclear America would need a command-and-control network, linked from city to city, state to state, base to base. The RAND proposal (Paul Baran) was made public in 1964. In the first place, the network would have no central authority. Furthermore, it would be designed from the beginning to operate while in tatters. In fall 1969, the first computer was installed in UCLA. By December 1969, there were four computers on the infant network, which was named ARPANET, after its Pentagon sponsor. In 1971 there were fifteen computers in ARPANET; by 1972, thirty-seven.
Throughout the '70s, ARPA's network grew. ARPANET itself formally expired in 1989, a happy victim of its own overwhelming success. The use of TCP/IP standards for computer networking is now global. In 1971, a mere twenty-one years ago, there were only four nodes in the ARPANET network. Today there are tens of thousands of nodes in the Internet, scattered over forty-two countries, with more coming on-line every day.
2.World Wide Web (WWW), computer-based network of information resources that combines text and multimedia. The information on the World Wide Web can be accessed and searched through the Internet, a global computer network.
