Answer to Question 2

A component is a relatively independent, encapsulated, and replaceable unit of software that provides services specified by one or more interfaces. Even though a component is not necessarily reusable, it is the ideal method for creating flexible systems.
Although anything that goes into building something bigger can be called a component, software components must have certain properties to qualify for the term: a component is a binary and relatively independent entity, a component's interface is separate from its implementation, and a component is replaceable.
Components are not the same as objects. A component might be composed of one object, many objects, or no objects at all. The other important difference is the binary nature of components: components are language-neutral, while objects are language-dependent.
A component usually has two sets of properties: functional (or what the component does) and extra-functional (that describe the component itself). While the rules governing the first set are well-defined by the underlying platforms, the second set usually does not enjoy a standard definition.
