Communication

Communication is a method of transferring information between two persons or organisms. Communication is possible using mutually understood behaviors such as signs, symbols, or language. In the year 1980, S. F. Scudder proposed communication theory. According to his ideas, all living beings on the earth communicate, but the methods of communication differ. Communication skills are now part of soft skills.
