Part 2 network

Key words: connection systems broadcasting television computers relations

Vocabulary: costly

Listen to a report about the word network. Supply the explanation for the word.

New things in this world change as fast as languages. Everyday, new words are created to deal with new ideas or new technologies. New meanings also are added to existing words. A dictionary published years ago may show one or two meanings for a word; a dictionary published today may list several more meanings for the same word.

Network is one such word. It combines two words. The first is “net” it means materials that are connected; The second is work. One meaning of work is a system. Network means a connection of systems that work together. The systems the network connect can be very different. For example radio and television stations can be connected in the network. So can computers and even people.

Word expert Milford Matthew found written uses of the word network in the late 1800s. The word then was used as a verb a word that shows action. At that time network means the connection of railroad or other vehicles used for travel. One publication said it is only a question of time when the railroad will network an area of the American west called the pan-handle. Another publication at that time said the complete areas are networked by trolley train, which are a kind of electric train.

Now we often hear network used in connection with broadcasting. The Barnhart Dictionary of New English says as early as 1914 people used it to mean a connected system of radio station. This meaning continues to be popular. A more modern use of the word network is linked to computers. A network is the system that links the number of computers together. Network make it possible for people who use computers to share information in costly equipment. Many companies and government agencies share the same computer network. The computers are linked through a main computer or through special lines. Some people are able to do their job from their home computers.

Computers network also permit an exchange of unofficial information and discussion between computer user. By ranking their computers telephone people can buy goods through their computers. They can send messages to friends in many countries.

Another modern use of the word network concerns relations between people. Ideas and information are exchanged by people in network to share interests and goals. Many Americans network to get better job or to meet new friends. Meeting new friends by networking is not work through is fun.

B 、 now listen again. Focus on the original use and modern use of the word network. Supply the missing information.
