Communication is the process of people reacting to and transmitting messages through verbal and nonverbal means. Verbal communication includes intrapersonal, interpersonal, public, and mass communication. Nonverbal communication conveys messages through silence, body language, facial expressions, paralanguage, touch, space, clothing, and symbols. Effective communication involves informing people, persuading ideas, integrating to achieve goals, creating relationships, helping decision making, and reducing misunderstandings.
