Communication involves the transfer of information from one entity to another and can take various forms. There are verbal and nonverbal types of communication, with verbal using words and nonverbal using gestures and body language. Communication also occurs on different levels, including intrapersonal (within oneself), interpersonal (between two people), mass (to a large audience), organizational (within a workplace), and flows upward, downward, diagonally, and laterally within an organization. Effective communication is important for employee trust, strong relationships, clarity, and collaboration.
