The basis of classification of governments as unitary and federal is the relationship between the center and the states. Let's understand this classification in detail:

Unitary Government:
- A unitary government is characterized by a centralized power structure where the central government holds most of the power and authority.
- In a unitary government, the central government has the ability to create or abolish local governments and can also alter their powers and functions.
- The central government exercises control over the entire territory and its administrative divisions, with the local governments acting as subordinate entities.
- The central government has the authority to make laws, collect taxes, and implement policies for the entire country or region.
- The local governments derive their power and authority from the central government and can be dissolved or restructured by the central government.

Federal Government:
- A federal government, on the other hand, is characterized by the division of powers between the central government and the regional or state governments.
- In a federal government, both the central government and the regional governments have their own independent powers and functions.
- The central government is responsible for matters that affect the entire country or region, such as defense, foreign affairs, and currency.
- The regional governments, also known as states or provinces, have their own jurisdiction over matters that are specific to their region, such as education, healthcare, and local infrastructure.
- The powers and functions of both the central and regional governments are defined and protected by the constitution.
- Neither the central government nor the regional governments have the authority to abolish or restructure each other as they are separate and independent entities.

Conclusion:
In conclusion, the basis of classification of governments as unitary and federal is the relationship between the center and the states. In a unitary government, the central government holds most of the power and authority and can create or dissolve local governments. In a federal government, the powers and functions are divided between the central government and the regional governments, with both being independent entities and having their own jurisdiction.
