Explanation:

The presidential form of government is that in which the executive is not responsible to the legislature. An example of such a system of Government is the United States of America (U.S.A).

The president is the real executive. There is no nominal or ceremonial executive. All the powers are vested in the hands of the president.

The powers of the three organs namely, legislature, executive and judiciary are separated and vested in different persons.

Though the three organs of the government are kept apart, they are also connected by the system of checks and balances. Each organ of government exercises checks on the other two organs so that a sort of balance is established.

The tenure of the president is fixed. The tenure of office cannot be lessened or increased under any circumstances. President can be removed by the legislature only by a process of impeachment.
