In your own words, what is the definition of a federal system of government?

A federal system of government is a type of governance where power and authority are divided and shared between a central or national government and individual regional or state governments. In this system, both levels of government have their own respective powers, responsibilities, and spheres of influence, which are defined and protected by a constitution or similar legal document. The central government is responsible for handling national-level matters such as defense, foreign affairs, and monetary policy, while the regional or state governments have the authority to manage local issues like education, healthcare, and transportation, within the framework set by the constitution. This distribution of power helps to maintain a balance between the central authority and the autonomy of regional or state governments, ensuring that decisions are made considering both national interests and the unique needs of different regions.
