Communication is the process of sharing ideas, information, and messages through various means such as writing, talking, nonverbal cues, images, and electronic signals. It is a vital part of human interaction in both personal and professional settings. Effective communication relies on components like completeness, conciseness, consideration, concreteness, clarity, courtesy, and correctness to transmit messages successfully. There are also several theories that aim to explain human communication and potential barriers that can interfere with the communication process.
