Explanation:

In a federal system, power is shared by a powerful central government and the state or local governments. States or provinces are given considerable autonomy, usually through their own legislatures, while in a confederation, power is shared by an alliance of independent states, distributed equally among the states. They voluntarily work together for some common purpose and agree to certain limits on their freedom of action. They might sign a treaty or a constitution under which the states agree to defend each other, trade with each other, use a common currency, etc. Membership is usually voluntary & a state can decide to leave at any time.
