Berlo's Model is a communication theory developed by David Berlo in 1960. It emphasizes the importance of the source, message, channel, and receiver in the communication process. The model suggests that effective communication occurs when all these elements are aligned, ensuring that the message is clear and understood by the receiver. The model is often represented as the acronym SMCR, which stands for Source, Message, Channel, and Receiver. Each component plays a crucial role: the source encodes the message, the message is the information conveyed, the channel is the medium used for transmission, and the receiver decodes the message. Understanding these elements helps improve communication effectiveness.
