Final answer:
A half-bit adder with two binary inputs and two binary outputs is incorrect; a half-adder has two inputs for binary digits and outputs a sum and carry.
Step-by-step explanation:
The statement that a half-bit adder circuit has two binary inputs and two binary outputs is False. A half-adder is a circuit that adds two single binary digits and produces a sum and a carry. Specifically, the half-adder has two inputs for the two binary digits and two outputs - one for the sum and another for the carry. The sum is the direct sum (XOR) of the two input bits, while the carry is the result of an AND operation on the same inputs.
