As we talked about communications media and hardware, we have occasionally referred to communications networks. Business workers often use networks, and chances are good that you will become acquainted with one or more types of communications networks in your job.
Information and resources gain in value if they can be shared. A network is simply a collection of data communications hardware, computers, communications software, and communications media connected in a meaningful group to allow users to share information and equipment. The three most common types of network are private, public, and international.
A private network is specifically designed to support the communications needs of a particular business organization. Many organizations with geographically separated facilities and a need for a large volume of data and voice communications implement or install their own private communication networks. The Southern Pacific Railroad was one of the first organizations to develop its own comprehensive microwave communications network to facilitate communication along all its rail lines. Its microwave towers can be seen along any of the major rail lines.
A public network, in contrast, is a comprehensive communications facility designed to provide subscribers (users who pay a fee) with voice and/or data communications over a large geographical area (in some cases coast to coast). Public networks such as bell Telephone and AT&T Communications are sometimes referred to as common carriers. Some public communications networks offer teleconferencing services- electronically linking several people by phone, computer, and video.
The term international network is used to describe a communication network specially designed to provide users with intercontinental voice and data communications facilities. The majority of these networks use undersea cable or satellite communications. Western union and RCA provide international networks.
