(1) Name the signal protocol that uses one voltage level to  represent a one and
    another to represent a zero.

    different values, zero and one.

    such as .com or .edu :


(1) Name the signal protocol that imposed the data on a clock signal. A one is
    transmitted when the carrier transistion is  low to high or stays high and a
