The removal of air (oxygen), which breaks the chemistry of fire, will put it out. The cooling of a fire or the removal of fuel, either of which stop the fire, will use physics to suppress it. For most fires, we can apply the principle of the fire triangle. This includes air (oxygen), heat and fuel at the corners (vertices) of the triangle. Remove one and the triangle falls apart, and this idea is used to attack and suppress fires.
