7. Indicate the type of shift register:
(a) into which a complete binary number can be loaded in one operation and then shifted out one
bit at a time;
(b) into which data can be entered only one bit at a time but have all data bits available as outputs;
(c) in which we have access to only the leftmost or rightmost flip-flop.
