6. A half adder is a basic logic
circuit that can add two
binary digits, or bits. It has
two inputs, A and B, and
two outputs, Sum and
Carry.

9. Full Adder Logic
Full Adder is the Adder that adds 3 binary
inputs and produces 2 outputs. It was
developed to overcome the complexity of
half adder, because Half Adder adds only 2
inputs and produces 2 outputs.

12. A half adder is a digital
circuit used to add two
binary numbers, A and B, to
produce two outputs: the
sum (S) and the carry (C).

13. The half adder circuit performs binary addition on
two single-bit binary numbers. The SUM output is
the least significant bit (LSB) of the result, while the
CARRY output is the most significant bit (MSB) of
the result, indicating whether there was a carry-over
from the addition of the two inputs.

15. A full adder is a fundamental
digital circuit used in the field
of electronics and computer
science. It is an essential
component in building more
complex arithmetic and logical
operations.

16. To build a full adder circuit, you will need the following
components:
Three input wires (A, B, C-in).
Two XOR gates.
Two AND gates.
One OR gate.
Two output wires (S, C-out).
