what is the main difference between a confederal system of government and a federal system of government?

In a federal system there is centralized authority

Explanation:

The federal government is the central government to the United States. State governments can run each state, but must obey federal laws. Local gov. run cities, towns, and counties, but must obey the state laws.

For the the confederal system; power is distributed equally among units, such as states. Each unit functions independently. The units agree to work together to meet mutual needs. There is little to no central authority.
