In the federal government, the national rule overrides the state rules, and there are multiple hierarchy levels with a central authority and the states both are sovereign. While in unitary government there is no hierarchy of sovereign powers and the states have no authority for passing their laws. The central government can order the state to do anything, the central government is more powerful in the Unitary system.
