Look at the ALU: 8a. How many input numbers (not counting control lines) can it handle? 8b. How many bits are in each input number? 8c. How many output numbers does it have? 8d. How many bits are in each output number? 8e. How many control lines does it have? 8f. How many operations can it support with that number of control lines?

Consider an ALU that can handle 64 operations on 32-bit numbers. As is conventional, assume all the operations are unary or binary (i.e., they need two operands at the most). 9a. How many data lines does it need for each input? 9b. How many data lines does it need for the output? 9c. How many control lines does it need?
