half adder is used to add two one bit input

Answer / mia

1) The ALU (arithmetic logic circuitry) of a computer uses half adder to compute the binary addition operation on two bits.

2) Half adder is used to make full adder as a full adder requires 3 inputs, the third input being an input carry i.e. we will be able to cascade the carry bit from one adder to the other.

3) Ripple carry adder is possible to create a logical circuit using multiple full adders to add N-bit numbers. Each full adder inputs a C(in), which is the C(out) of the previous adder. This kind of adder is called RIPPLE CARRY ADDER, since each carry bit "ripples" to the next full adder. Note that the first full adder (and only the first) may be replaced by a half adder.
