Difference Between Half Adder And Full Adder in Tabular Form
| S.No. | Basic Terms | Half Adder | Full Adder |
| 1. | Circuit |
|
|
| 2. | Working | A combinational logic circuit that performs the addition of two data bits, A and B, is called a half-adder. Addition will result in two output bits; one of which is the sum bit, S, and the other is the carry bit, C. | The half-adder does not take the carry bit from its previous stage into account. This carry bit from its previous stage is called carry-in bit. A combinational logic circuit that adds two data bits, A and B, and a carry-in bit, C , is called a full-adder. |
| 3. | Inputs | 2 | 3 |
| 4. | Output | 2 | 2 |
| 5. | Carry | Carry not Used | Previews Carry is Used |
| 6. | No. Of Components | 1 : Xor 1 : And | 2 : Xor 2 : And 1: Or |
| 7. | Boolean Expression | S = A ⊕ B C = A.B | Sum =A ⊕ B ⊕ C Carry = A.B + (A ⊕ B).C |
| 8. | Applications | Calculators, computers, digital measuring devices etc. | Multiple bit addition, digital processors etc. |

Your full adder diagram is wrong. C doesn’t end with an XOR but with an OR.
