A * B is a numerical multiplication. If the (perl) values of A and B can only be 1 and 0 then this is equivalent to a Boolean AND.

A & B is a bitwise AND. Again, if 1 and 0 are the only values this is also equivalent to a Boolean AND.

Whether or not these expressions are entirely equivalent depends on the restrictions of the values to the binary set {0, 1}.
