1-Explain why a software component, which can have a complex internal structure (classes, objects, etc.), must be deployed as a single unit (only part of its structure cannot be deployed).

2-Explain why we say that object-oriented programming languages (POO) do not define a unit of composition independent of elements of use in applications that are derived with such languages.

3-A software component can contain objects that are created inside it and are visible to the customers of the component: does this not violate the property that says that the components cannot contain a state that is observable from the outside of the component?

4-Explain what problems the use of polymorphism used in OOP would present if we try to use it in COP.
