What actions occurs in presidential gov but not in Parliament?

In a presidential system, the president serves as both the head of state and government, allowing for direct executive decision-making and independent authority, which is not typically seen in parliamentary systems where the executive is derived from the legislative branch. Additionally, the president can veto legislation independently, whereas in parliamentary systems, the head of government (usually the prime minister) must maintain the confidence of the legislature. Furthermore, presidential systems often have fixed electoral terms, making it more challenging to remove a sitting president compared to a prime minister in a parliamentary system, who can be ousted through a vote of no confidence.
