Half Adder And Full Adder Definition. The two inputs are a and b and the third input is a carry input c in. On the contrary full adder operates on 3 inputs.

The two inputs are a and b and the third input is a carry input c in. If any carry is obtained in the addition process it is given to full adder as an input and it adds that carry along with other inputs. The output carry is designated as c out and the normal output is designated as s.
The main difference between a half adder and a full adder is that the full adder has three inputs and two outputs.
The main difference between a half adder and a full adder is that the full adder has three inputs and two outputs. Another significant difference between half adder and full adder is that half adder consists of one ex or gate and one and gate while full adder consists of two ex or gates two and gates and one or gate. The truth table of the full adder circuit is shown below. Both the half adder and full adder hardware architecture is not the same.
