The basic structure and functions of the United States Federal Government
By Robert Longley, About.com Guide
The Executive Branch

The Executive Branch of government is headed by the President of the United States, who also acts as the head of state in diplomatic relations and as Commander-in-Chief of all U.S. branches of the armed forces. The President is responsible for implementing and enforcing the laws written by Congress and, to that end, appoints the heads of the federal agencies, including the Cabinet. The Vice President is also part of the Executive Branch, and must remain ready to assume the presidency should the need arise.

The Judicial Branch

The laws of the United States are a complex tapestry weaving through history, sometimes vague, sometimes specific and often confusing. It's up to the federal judicial system to sort through this web of legislation and decide what is constitutional and what is not.

Federalism

The U.S. Constitution establishes a government based on "federalism," or the sharing of power between the national, and state (and local) governments. Our power-sharing form of government is the opposite of "centralized" governments, such as those in England and France, under which national government maintains total power.
