Over time, the equilibrium price of a gigabyte of computer memory has fallen while the equilibrium quantity purchased has increased. based on this we can conclude that:

Answer: Increases in the supply of computer memory have exceeded increases in demand.

Explanation: When the rise in demand for a good is lower than the rise in the supply of the good, the equilibrium price tends to fall. However, the equilibrium quantity increases. Thus, when increases in the supply of computer memory exceeds increases in demand. for computer memory, equilibrium price falls and the equilibrium quantity rises.
