Communication+Models

a representation of specific object or event in idealistic form.
 * what is a model ?**


 * Advantages of models ?**
 * 1) allow us to ask questions.
 * 2) lead us to new discoveries.
 * 3) clarify complexity.
 * Limitations of models ?**
 * 1) could cause oversimplification.
 * 2) could lead to confusion.
 * 3) premature closure.


 * **__Classical Communication models__ "Aristotle":**

**Invention "discoveries", logos which inheres the content of the message**
 * --> Arrangement the arrangement of the discoveries in the message strategically **
 * -> Style "clothes ideas in clear and compelling words to be understood **
 * --> delivery of the message . **
 * ethos : affect the speaker, Pathos : affect the audience . **


 * __**Mathematical Model "**__**Shannon-Weaver" :**
 * Strengths :**
 * 1.the most common model used in low level communication.**
 * 2.significant development "Many behavioral sciences adapted it "**
 * 3.significant heuristic value.**
 * 4.taken as an approximation of human communication process.**
 * 5. the concept of this model became staple of communication researches**
 * (X) ENTROPY : The degree of uncertainty in any system.**
 * (X) REDUNDANCY : The degree to which information is not unique in a system.**
 * (X) NOIS : The measure of information is not related to a message .**
 * (X) CHANNEL CAPACITY : The maximum amount of information channel can carry .**
 * NOTE : the greater uncertainty the more information.**


 * Weaknesses :**
 * 1. Only formal**
 * 2. Not analogous for human communications.**
 * 3.Static and linear .**


 * Berlo's model :**

This model considered the word " SOURCE " as any source of information ,so its a dynamic word ( source could be electronic source, oral , written , or any other source of information " . also we notice that both sender and receiver must have the same communication skills so that the message delivered and understood by the receiver. Berlo's mode is a behavioral approach . the sender have the full responsibility of the message that the receiver will understand it.
