What is the difference between "ProductCreator" and "ComponentCreator"?

I am trying to learn VC atm. What is the difference between “ProductCreator” and “ComponentCreator” and when do you use which?

Hy,

the mighty help says:

If you use ProcessModelling you need to create products.
In some other cases you need to create components…

Thank you, I already thought it was as simple as that but I wasn’t sure.
