How do the presidential and parliamentary forms of government differ from one another?

In a Presidential system, the Chief Executive is elected by the People. In a Parliamentary system, the people vote for their legislators and the legislators elect from their ranks the Chief Executive (often called a Prime Minister)

Presidential and parliamentary forms of government differ from one another in that there is only one President at a time who is indirectly elected by the people (citizens). The president is the executive branch of

government, tasked with executing federal laws and overseeing the military.

Parliament makes laws, represents the population, uses inquiries and hearings to oversee the government, and does not have as strict separation of power laws.
