Abstrakt: The zero-divisor graph of an associative ring R is defined as follows. The vertices of the graph are all the nonzero elements of the ring. Two different vertices x and y of the graph are connected by an edge if and only if xy = 0 or yx = 0. In this paper, we give the complete description of varieties of associative rings all of whose finite rings are uniquely determined by their zero-divisor graphs. [ABSTRACT FROM AUTHOR]
