There is an important distinction between an entity, a component, and a
component instance in VHDL. The entity describes a design interface, the
component describes the interface of an entity that will be used as an
instance (or a sub-block), and the component instance is a distinct copy of
the component that has been connected to other parts and signals. To compare
these with the process of bread board design with off-the-self parts. The
entity and architecture is like the data book describing the interface and
schematics of how the part works. The component is like the short pin
listing that comes with the part to describe how it should be connected. The
component instance is the actual part itself, of which you may have many
that each operate independently.

nije potrebno da uvodis komponente, ako im ne vidis smisao :)
