Answer to Question 1

A real object is a thing, but more specifically it is something that is perceived as an entity and referred to by name. A virtual object is an entity in a virtual system similar to objects in the real world. Virtual objects are created from classes that act as templates. All characteristics of real objects apply to virtual objects, but since by definition virtual objects are not real, certain concepts have to be discussed from a slightly different viewpoint. When a hospital treats a patient, it attends to a real object, even though the attributes and the behavior of the real patient are abstracted and generalized into the class. But when the hospital wants to track the patient's medical history, it is no longer concerned with a real object, but with a virtual object that has only those attributes that the hospital considers relevant to an instance of the patient class. When you enroll in a college, you become a student by virtue of the fact that the college agrees to abstract certain attributes from you (the real object), place them in a template, and instantiate a virtual student object. To open an account, a bank must use a customer template and one or more account templates. We do not abstract or generalize virtual objects into classes, but create them from templates or classes that are already abstract and general.
