What is defined as the external source in communication?

In communication, the external source refers to the origin of the information or ideas that are being conveyed. In this context, the correct term is "source," which represents the individual or entity that initiates the message. The source is responsible for encoding the message, determining how it will be presented, and ensuring it is delivered to the intended audience.

The message itself is the content or information being transmitted, but it does not represent the external source. The receiver is the individual or audience who interprets the message, while the channel is the medium through which the message is delivered, such as spoken words, written text, or visual images. Understanding the role of the source is crucial as it shapes the communication process and influences how the message is received and understood.
