The exchange of information between the members with the assistance of electronic transmission is very fast. The data are also available in written form in printouts. “Network” is a system of transmission linking facilities for automatic data processing. In this way different computers are connected, permitting data exchange and processing over long distances. Telecommunication is possible only when there is such a network available. The telephone is the simplest and the best known network.

In addition, there is also a separate clear data network for the exchange of data which works digitally. In this way a high transmission speed is achieved and there is a very low ratio of errors during transmission. There are different types of networks which can be used for telecommunication purposes either separately or combined. The text on the screen is provided by a telephone network or any other network.
