A change in supply is a shift of the supply curve. A change in quantity supplied is a movement along a given supply curve.
------------------------
Change in supply: Changes in variables other than the price of a good, such as input prices or technological advances, lead to a change in supply. This corresponds to a shift of the entire supply curve.
Change in quantity supplied: Changes in the price of a good lead to a change in the quantity supplied of that good. This corresponds to a movement along a given supply curve.
