Question

How is federal government organised?

Answer 1

The Federal Government of the United States is the central government entity established by the United States Constitution, which shares sovereignty over the United States with the governments of the individual U.S. states. The federal government has three branches: the legislative, executive, and judicial. Through a system of separation of powers and the system of "checks and balances," each of these branches has some authority to act on its own, some authority to regulate the other two branches, and has some of its own authority, in turn, regulated by the other branches. The policies of the federal government have a broad impact on both the domestic and foreign affairs of the United States. In addition, the powers of the federal government as a whole are limited by the Constitution, which, per the Tenth Amendment, states that all powers not expressly assigned to the federal government are reserved to the states or to the people.
