Whats the three-part government of the british colonies?

The three parts of the government were a Governor, a Council of Advisers, and an Elected Assembly. The governor was something like the president, that is the commander in chief with the power to veto. The Council and the Assembly were like the upper and the lower houses of the parliament. The lower was closely connected to the will and the demands of the people while the upper was more into legislature. your welcome
