Final answer:
The sender or originator is one of the two primary elements of a 2-way conversation and is responsible for initiating the communication and transmitting the message to the receiver.
Step-by-step explanation:
One of the two primary elements of a 2-way conversation that originates messages to a receiver is known as the sender or originator. In effective communication, the sender is responsible for initiating the conversation and transmitting thoughts, ideas, or information to others. This can occur through various methods, from in-person conversations to digital communication such as social media or text messages. It's important for the sender to consider the voice and tone of their message because these elements can significantly impact how the receiver understands and connects with the message.
In the context of social media, the sender is not only conveying a message to a real audience but also to an anticipated audience, whom they may not personally know yet hope to reach or engage. For example, a social media post is crafted with an anticipated group of followers or a broader public in mind, with particular considerations on how they might respond to or perceive the content shared.
