Final answer:
Both Schramm's model and the Shannon and Weaver model of communication feature a sender, message, receiver, and the concept of noise. Schramm's model builds on Shannon and Weaver's by including feedback, but they share a fundamental structure.
Step-by-step explanation:
The similarities between the Schramm's model and the Shannon and Weaver model of communication are foundational in understanding communication theory. Both models emphasize the process of communication as involving a sender, message, and receiver.
Additionally, these models both acknowledge the potential for noise to disrupt the communication process. The Shannon and Weaver model is often appreciated for its simplicity and general applicability, while Schramm's model adds the dimension of feedback, indicating a more dynamic interaction between sender and receiver.
However, Schramm's model could be seen as an extension of the Shannon and Weaver model, indicating that they share a fundamental structure.
