Communication involves the exchange of ideas between two or more people. It is defined as a process where people exchange thoughts, facts, feelings, and meanings through messages to develop a common understanding. Some key aspects of communication are that it requires a minimum of two participants, an exchange of ideas or information, and mutual understanding between the sender and receiver. Communication can occur through both direct face-to-face interaction or indirectly through channels like phone calls, emails, or other means. It is also a continuous process and can involve both verbal and nonverbal exchange such as through words, symbols, gestures, or expressions.
