M+1 full adders
A 4bit parallel adder can be implemented by connecting four (4) full adders in parallel that will count from zero to fifteen.
A full adder takes two inputs plus carry in and produces one output plus carry out. You need four full adders to add two 4 bit words. (No half adders required.)Or: for the lowest bit you can use a half-adder (no input carry).
serial adder: 1) Slower 2) It uses shift registers 3) IT requires one full adder circuit. 4) It is sequential circuit. 5) Time required for addition depends on number of bits. Parallel adder: 1) Faster 2) It uses registers with parallel load capacity 3) No. of full adder circuit is equal to no. of bits in binary adder. 4)It is a combinational circuit 5)Time required does not depend on the number of bits
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

Yes and no. The ripple carry adder is one type of parallel adder. Other parallel adder types include the pipelined parallel adder and the carry look-ahead adderamongst others.

Connect two half Adders with an OR gate to make a Full Adder.
there are no adders for free
Some key differences between a Serial and Parallel Adder are that a Serial Adder is slower, a Parallel adder is a combinational circuit and the time required for addition depends on the number of bits in a Serial, but not a Parallel. A Serial Adder is a sequential circuit while a Parallel is a combinational circuit.
Adders are a type of snake. If an adder encountered a vole, it would eat the vole. A vole would not hunt and eat an adder.
A full adder takes two inputs plus carry in and produces one output plus carry out. You need four full adders to add two 4 bit words. (No half adders required.)Or: for the lowest bit you can use a half-adder (no input carry).
The common name for a puff adder is simply "puff adder."
A species such as an adder can be classified by phylum, but an organ such as a tongue does not get its own phylum, it is just part of the adder. Adders are classified as reptiles.
It is a digital circuit that produces the arithmetic sum of two binary number .It can be constructed with the full adders connected in cascade,with the output carry from each full adder connected to the input carry of the next full adder in the chain.
