Hereto, belong also research works on the essence and listings of numerous definitions of communication. Providing the answer to the second question, the paper will pay attention to the origin of theory communication as a separate subject of education taught and learnt at colleges and universities. Most of all, the principal attention will be devoted to supply an answer to the third question.
