Which of the following is NOT a part of the process model of communication?

In the context of the process model of communication, key components include the sender, receiver, and feedback. The sender is the individual or entity that initiates the communication by transmitting a message. The receiver, on the other hand, is the individual or entity that decodes or interprets the message. Feedback is essential as it allows the sender to understand how the message was received and whether it was understood correctly, thus facilitating effective communication.

Measurement, while important in various contexts, does not directly fit into the fundamental components of the communication process model. It refers to quantifying or assessing certain metrics, which is not a core element of communication itself but might be considered when evaluating the effectiveness of communication methods or outcomes. Therefore, recognizing that measurement is not a key component of the basic communication model clarifies why it does not belong alongside the concepts of sender, receiver, and feedback.
