According to the Shannon and Weaver model, which of the following statements are true?

1.It distinguishes the technical, semantic and influential (effectiveness) levels

2.Entropy and randomness are relevant to messages

3.Their model was the first to highlight the role of noise in communication

4.This communication is called telegraphed communication

A1, 2 and 3

B1, 2, 3 and 4 ✓ Correct

C2, 3 and 4

D3 and 4

Correct answer: (B) 1, 2, 3 and 4

Explanation

Statement 1 is true: the Shannon and Weaver model distinguishes technical, semantic and effectiveness levels.

Statement 2 is true: entropy and randomness are relevant to messages in this information model.

Statement 3 is true: theirs was the first model to highlight the role of noise in communication.

Statement 4 is true: this scheme grew from telegraphed communication and is often called telegraphed.

Entropy here measures disorder or unpredictability in a message.

The model treats the sender as active while the receiver stays comparatively passive.
