Federalism is a form of organization of the State in which there is a government that exercises the functions of a centralizing State. But at the same time that there is a central power, there is a division of power between the units that form it.
These units, when they are united and regulated by a common Federal Constitution, form a Federal State.
In Federalism, the division of power occurs through delegation, that is, the central political power is shared by each of the federative units.
