In a parliamentary system, the executive comes from the legislature and stays in power only while the legislature supports it. The prime minister and cabinet are usually members of the parliament, and they can be removed by a vote of no confidence, making the government directly answerable to the legislature. In a presidential system, the president is elected separately from the legislature and serves a fixed term, creating a clearer separation of powers; the president appoints a cabinet but is not typically removable by a simple legislative vote, since removal usually comes only through impeachment.
