Bidirectional communication refers to a two-way exchange of information where both parties can send and receive messages. This type of communication is essential in various contexts, such as in telecommunications, where devices like phones allow users to talk and listen simultaneously. It fosters better understanding and collaboration between individuals or groups. In contrast to unidirectional communication, where information flows in one direction, bidirectional communication encourages feedback and interaction. This is important in settings like education, where teachers and students engage in discussions, enhancing learning and comprehension. Overall, bidirectional communication promotes effective dialogue and relationship-building.
