How is a unitary system of government different from a federal system ?

A unitary system of government is a system in which all power is centralized in a single, central government, which delegates authority to local governments as necessary. In a unitary system, local governments do not have constitutional standing and can be created or abolished by the central government.

In contrast, a federal system of government is a system in which power is divided between a central government and regional governments, such as states or provinces. Both levels of government have their own areas of authority and are considered independent in their own spheres.

The key difference between a unitary system and a federal system lies in the distribution of power and authority. In a unitary system, power is concentrated in the hands of the central government, while in a federal system, power is distributed between the central government and regional governments.
