Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver has understood the message of the sender.
Communication is the process where the one person is expressing his or her idea and the other one is listening to the idea being expressed by the one who is talking. That is how you define communication. When this results to have an understanding to both of them, therefore there is already a communication. In other words, when a person is talking, the other person should listen so that he will understand to what the other person is talking about. When a person talks and nobody listens, then there is no communication happening because there is no understanding. The people just heard what the person in front of them is talking but they do not listen to it well that is why they do not understand about the topic.
