Full adder circuit:
Full adder reduces circuit complexibility. It can be used to construct a ripple carry counter to add an n-bit number. Thus it is used in the ALU also. It is used in Processor chip like Snapdragon, Exynous or Intel pentium for CPU part . Which consists of ALU (Arithmetic Block unit) . This Block is used to make operations like Add, subtract, Multiply etcA full adder adds binary numbers and accounts for values carried in as well as out. A one-bit full adder adds three one-bit numbers, often written as A, B, and Cin; A and B are the operands, and Cin is a bit carried in from the previous less significant stage.The full adder is usually a component in a cascade of adders, which add 8, 16, 32, etc. bit binary numbers.
to add two bit no. in computer chip half adder is use.
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.
Two half adders, an OR gate, and a delay.
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.
A full adder has a sum bit and a carry bit. A half adder just has a sum bit.

The circuit which adds two single bit binary numbers and produce a sum and carry is a half adder circuit.

No. A full adder is two half adders with a carry circuit to combine the two carries together.

It is false. A half adder is a computer circuit capable of adding two binary bits
An adder-subtractor is a circuit capable of subtracting or adding binary numbers. The application of a 4-bit adder and subtractor is for use as part of the core of an ALU, or arithmetic logic unit.
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
