Half adder and full adder difference

we all know that a half adder is a one types of combinational logic circuit with two input and also have two output wheres the full adder is add three one-bit binary numbers, two is operands and a carry bit but in output is to be two numbers, sum and carry bit, this is the main difference between them. This article gives information about the difference between the half adder and full adder to know more details about it.

Definition :
  • Half adder: Half adder is a combinational logic circuit which adds two 1 bit digits
  • Full adder: Full adder is a combinational circuit which adds three 1 bit digits
Hardware :
  • Half adder: It consists of one EX-OR gate and one AND gate 
  • Full adder: It consists two EX-OR, two AND gate, and one OR gate
Carry addition :
  • Half adder: Carry generated from a previous addition is not added in the next step
  • Full adder: Carry generated from a previous addition in the next step
Application : 
  • Half adder: Calculator, computers, digital measuring devices etc
  • Full adder: Multiple bit addition, digital processor
