From wikipedia:
A half adder is a logical circuit that performs an addition operation on two binary digits. The half adder produces a sum and a carry value which are both binary digits.
A full adder is a logical circuit that performs an addition operation on three binary digits. The full adder produces a sum and carry value, which are both binary digits. It can be combined with other full adders or work on its own.

∙ 13y agohalf adder is the computational device that adds two binary digits while full adder is the computational device that adds three binary digits.

∙ 11y agohalf adder does not have a carry in (Cin) while a full adder has the Cin

The full adder can account for carry-in and carry-out. The half adder can't.

A half adder has two inputs and two outputs whereas full adder has three inputs and two outputs.

Why full adder is better then half adder?
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
Presentation on half adder and full adder?
hii this is use full persentation
Why you use half adder after the arrival of full adder?
The full adder takes care of everything, A, B, CarryIN, Sum, and CarryOut. I don't see why you would need a half adder after using a full adder, unless you were trying to process look-ahead carry, but that requires more than just a half adder.
Why half adder is so called?
A full adder has a sum bit and a carry bit. A half adder just has a sum bit.
What are disadvantages of full adder using two half adder?
more logic gates are used instead
Why full adder is better then half adder?
Full adder is better than half adder because in half adder we can perform operation on only two digits and in full adder we can perform operation on three binary digits.
Define half adder?
half adder is computational device which is used to add two binary digits
Can full adder become half adder?
No. A full adder is two half adders with a carry circuit to combine the two carries together.

What are the applications of full adder and half adder?
they are integrated in the calculators
What are applications of half adder and full adder?

What is the basic differences between full adder and half adder?
Number of input bits. Half adder: (Cout,Q) := A+B Full adder: (Cout,Q) := A+B+Cin
Why you use half adder after the arrival of full adder?
The full adder takes care of everything, A, B, CarryIN, Sum, and CarryOut. I don't see why you would need a half adder after using a full adder, unless you were trying to process look-ahead carry, but that requires more than just a half adder.
Why we use half adder even when full adder is more usefull?
A half adder has less components, and may therefore be cheaper. So, in cases where all you need is a half adder, it may be more convenient to use a half adder. Or it may be more convenient to mass-produce only the full adders, since a full adder can work as a half-adder as well.Also, in introductory electronics textbooks, the half-adder would be introduced first, just because it is simpler.
What are the advantages of half and full adder circuit?
Do you mean :- how to get full adders by using half-adders? For this question refer following answer - A full-adder can be obtained by combining two half-adders and one or gate. Details on full-adder and half-adder can be referenced from following link http://www.fullchipdesign.com/fulladder.htm
How a Full Adder with the help of two Half Adders?
Connect two half Adders with an OR gate to make a Full Adder.
Why half adder is so called?
A full adder has a sum bit and a carry bit. A half adder just has a sum bit.
