Federal Departments are key components of the U.S. government that manage various public services and enforce laws. Each department is headed by a Secretary who is a member of the President's Cabinet, responsible for implementing policies and overseeing operations within their respective areas. These departments cover a wide range of functions, including defense, education, and health. They play a crucial role in shaping national policy and delivering services to citizens, ensuring that government initiatives align with the needs of the public and the country as a whole.
