Analytical Chemistry Question

(6) An electrochemistry experiment communicates with a computer using digital signal transmission. The number 50 is used to represent an electrical current of 50 milliamps (mA). Assume it takes 2.25 ns to transmit a single bit of data. (a) How long does it take to transmit the number 50 in serial form? (b) How long does it take to transmit the number 50 in parallel form using 8 wires? (c) Give one advantage and one disadvantage of parallel digital signal transmission versus serial digital signal transmission
