Half Adder And Full Adder Definition. The two inputs are a and b and the third input is a carry input c in. The truth table of the full adder circuit is shown below.

The truth table of the full adder circuit is shown below. 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 major difference between the half adder and the full adder is that the half adder operates on 2 inputs.
Both the half adder and full adder hardware architecture is not the same.
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. More specifically we can say that half adder adds only 2 one bit numbers and the previously generated carry bit is not added in its case. Both the half adder and full adder hardware architecture is not the same. Half adder generates sum carry by adding two binary inputs whereas the full adder is used to generate sum carry by adding three binary inputs.
