What is defined as the process of sending and receiving messages?

The process of sending and receiving messages is most accurately defined as communication. Communication encompasses the entire exchange of information between individuals or groups, whether it's verbal, non-verbal, written, or visual. It involves not only the transmission of a message from a sender to a receiver but also the feedback mechanism that allows the receiver to respond, thus confirming or modifying the understanding of the initial message.

This definition includes various forms through which messages can be conveyed, such as speaking, writing, or even body language, emphasizing the importance of both the act of sending and the interpretation of the message received.

While terms like conversation, interaction, and dialogue may imply a form of communication, they each refer to specific types or aspects of communication rather than the overarching concept. For instance, conversation typically implies an informal exchange of ideas, interaction can denote any kind of engagement between parties, and dialogue suggests a more structured discussion aimed at mutual understanding—all of which are components or styles of communication rather than the complete process itself. Thus, communication is the broadest and most inclusive term for this process.
