Unidirectional communication is a one-way form of communication where information flows in a single direction, from the sender to the receiver. This type of communication does not allow for feedback or interaction from the receiver, making it a straightforward way to convey messages. Examples include television broadcasts, radio announcements, and public speeches. In unidirectional communication, the sender controls the content and delivery of the message, while the receiver passively receives the information. This method is often used in mass communication settings, such as advertising campaigns or educational lectures, where the goal is to inform a large audience without expecting immediate responses.
