Concepts on components decomposition

Question: Explain the concept of decomposing a Component (from its largest form to its smallest), and how the internal and external views apply to this concept (decomposition).

Anyone can help me with this question ?

What part of the question do you need assistance with?

My initial reaction was that you want to take a composite structure and iterate through its components. I don’t know what internal and external views mean in this context so we may need additional information for this question.
