We study the multiplicativity and its variations of weak multiplicativity and very weak multiplicativity, analyze the role of connectivity condition in their definitions, and explore the relationship between them. New classes of multiplicative graphs and digraphs as well as weak multiplicative graphs and digraphs are obtained.
