(1). What do you mean by Object Oriented Modelling ? Discuss various object Modeling techniques.

(2). Suppose a computer is built out of one or more CPUs, sound card and video. Model the system with representive classes and draw the class diagram.

(3).  What is Dynamic Model? Explain how it is different from Object model.

(4). What is a Class diagram? Explain how classes are identified designing of an object oriented system with the help of an example.
