The president is the title of the head of state of the Republic, and is called the "commander-in-chief" in Japan or South Korea. People's Republic of China (PRC) calls its head of state "President" and other heads of state "Presidents".

In presidential countries, the president is also the head of government, even dictatorship. The United States, Indonesia, the Philippines, Egypt and many countries in Latin America have a presidential system.

In parliamentary countries, the president is only a symbolic position as the head of state, and it is the prime minister (or cabinet) who really exercises administrative power, such as Germany, Italy, India, Singapore and Israel.

In semi-presidential countries, the division of power between the president and the prime minister is different in different countries, and the measure of "duality of legitimacy" is implemented, but the power of the president is generally greater than that of the prime minister. For example, French, Russian, Korean, People's Republic of China (PRC) and Taiwan Province Province of the Republic of China can also be regarded as semi-presidential system or similar to semi-presidential system.

In a committee-based country, the chairman (president) of the committee is similar to the legal presidential system, and is the head of state and government; But its power and status are not higher than other members, just like the head of state under the cabinet system. Switzerland is the only country that implements this system.
