### 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, Cin , 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 | 3 : Xor 2 : And |

7. | Boolean Expression | S = A ⊕ B C = AB | S =A ⊕ B C = AB + BC + AC |

8. | Applications | Calculators, computers, digital measuring devices etc. | Multiple bit addition, digital processors etc. |
