Answer:
The most common communication model is the Early Shannon and Weaver Model but the most accurate, in my opinion, is the Schram Model in which a source encodes a message, which is sent through a channel and the channel contains some sort of noise or interference whether it be static over the phone or birds chirping outside. The receiver then decodes that message and interprets it in some way. The receiver then sends their feedback, back to the original sender in the channel which contains noise.
