What is the difference between a parliamentary and a presidential government?

A parliamentary government or a parliamentary system is referred to as the executive branch of the government of which the legitimacy is derived from the legislature (parliament) itself and a presidential government is a governmental body of which the leader is the president

"In a parliamentary government, the two main leaders, a head of state and a head of government, are not the same, but in a presidential government one person holds both powerful positions.

"In a parliamentary government, the head of government is a prime minister whereas in a presidential government it is a president.

"The prime minister is a member of the parliament who is elected upon by fellow congress members while a president is not always considered a member of the parliament.

"In a parliamentary government, the head of state is usually someone from the royal bloodline; a king, a queen, a prince or a princess.

"In a parliamentary government, the parliament is inferior to the legislature of the country while the situation may be different in a presidential government.

A prime minister, for the actions taken by the government, is answerable to the parliament whereas a president is rather responsible to the public who cast their vote on him/her.
