Arrange the following communication models in chronological order :
(i) Conceptual model
(ii) Functional model
(iii) Mathematical model
(iv) Systematic model of communication
Codes :
Answer: D
The keyed answer is (i) (ii) (iii) (iv): conceptual, functional, mathematical, systematic. I could not confirm this sequence, so the explanation says what is and is not settled.
The four names are classes of communication models, not single models, and no standard reference dates each class. A search of the literature found dated lists of individual models (for example Lasswell 1948, Shannon and Weaver 1948-49, Osgood and Schramm 1954), but nothing that puts conceptual, functional, mathematical and systematic models in an order. The University's key follows the order in which the classes are listed, and nothing found shows it to be wrong, so it is kept as printed.
The other options reorder the same four items, for example by starting with the systematic model, and no source supports any of them over the key.
