Amount of information in a message: Amount of uncertainty it reduces3. Fidelity of a message accuracy of message transmission: amount of information sent equals amount of information received; the greater the uncertainty or entropy reduced, the more information transmitted by the message.Perfect communication: amount of information sent = amount of information received5. Noise: technical or human distortions in the system.Strengths & Weaknesses of the Mathematical ModelStrengths:Provides an objective measure (quantity) of communication effectiveness.Weakness:Meanings of messages are not consideredOne-way communicationCOMSOC 321 1st Edition Lecture 2Chapter 1: Introduction 4.
