Types of communication and their characteristics

The technical means used to deliver information include a variety of communications. They assume the use of facsimile, telephone, telegraph machines , computers equipped with modems, etc. All these devices make it possible to organize various types of communication. When transmitting information to the user, the methods used for the session are not known.

Traditional types of communication are divided into:

- postal (transferring graphic and alphanumeric information);

- telephone (transmitting speech);

- telegraphic (intended for the transfer of alphanumeric messages);

- Facsimile (facilitating the transfer of graphic and alphanumeric information);

- radio relay and satellite communication.

In this case, the methods of information transfer can be wired (telegraph, telephone, etc.), as well as wireless. In the second type of connection, in turn, separate groups are classified (radio, radio relay and satellite systems). In this case, the transmission of speech, for example, is possible through almost any of the species.

Modern types of communication are divided into:

- telephone;

-computer telephony;

- radio telephone;

- radiotelephone cellular communication system;

-systems included in the Wi-Fi standard.

This kind of connection, like telephone, is the most widely used and widespread. It is used not only for contacts between people, but also for more efficient management of enterprises, the administrative building, as well as for financial and economic activities. Depending on the type of use of the phone, the connection is divided into two main types:

- for general use (international, intercity and city);

- internal, used within only one organization.

In the technology of computer telephony, the main role is assigned to a personal computer. The use of this type of communication contributes to a significant acceleration of the process of operational management of the enterprise, while increasing the quality and efficiency of administration with a minimum of costs. The use of modern computer technology allows you to reduce the amount to pay for long-distance and international negotiations.

Such types of communication, as radiotelephone, use in the process of information transfer wireless systems. This allows you to significantly reduce the costs incurred to install expensive communications and their subsequent maintenance. This type of communication is very mobile and can be quickly organized in any locality. At present, radiotelephone communication is an excellent alternative to wired telephony.

The reason for the emergence of cellular communications is the need to create an extensive network of radiotelephone mobile communications. At present, the use of this method of information transfer is carried out in more than one hundred and forty countries of the globe, on all continents.

To modern wireless technology is also Wi-Fi. The principle of information transfer in this form of communication is based on the connection in a network of a number of computers or their connection to the Internet.
