Final answer:
Original jurisdiction is a court's power to hear a case for the first time, while appellate jurisdiction is its power to hear a case on appeal. District courts have original jurisdiction, while appellate courts have appellate jurisdiction. The Supreme Court has both original and appellate jurisdiction.
Step-by-step explanation:
Original jurisdiction and appellate jurisdiction are two types of jurisdiction in the federal court system. Original jurisdiction refers to a court's power to hear a case for the first time, while appellate jurisdiction refers to a court's power to hear a case on appeal from a lower court. In the federal court system, district courts have original jurisdiction, while appellate courts have appellate jurisdiction. The Supreme Court has both original jurisdiction for certain cases, such as those involving a state or ambassadors, and appellate jurisdiction for all other cases.
