Human communication is a set of activities in which language communication is only one of the components, it is right and the most important because of its complexity. According to the Dictionary of social psychology, communication is defined as a “fundamental way of psychological interaction of persons, achieved through the symbols and social-generalized meanings of reality, in order to achieve stability or changes in individual or group behavior". The exchange of information between two elements is based on the inter-human communication, on the specific set of psychomotor processes in which the main channel is the verbal one, to which the nonverbal channels are added. Communication has been defined according to the conception of professor M. Zlate often as a particular form of the exchange relationship between two or more persons, two or more groups. "To live means to communicate. Any communication activity is based on the understanding of the others, but also our understanding by the others. We communicate to discover each other's needs and to share them with us".
