Federal institutions are organizations created by the national government to implement laws and policies. They include various branches and agencies, such as the Executive Branch, Legislative Branch, and Judicial Branch. These institutions work together to ensure the functioning of the government and the delivery of services to citizens. Each federal institution has specific roles and responsibilities. For example, the Congress makes laws, while the Supreme Court interprets them. Agencies like the Federal Bureau of Investigation (FBI) and the Environmental Protection Agency (EPA) focus on particular areas, such as law enforcement and environmental protection, respectively.
