Detailed explanation-1: -It is done by a 1 bit flip flop and several shift registers and pair of bits added simultaneously during each clock cycle.
Detailed explanation-2: -A binary parallel adder is a digital circuit that adds two binary numbers in parallel form and produces the arithmetic sum of those numbers in parallel form. It consists of full adders connected in a chain, with the output carry from each full-adder connected to the input carry of the next full-adder in the chain.
Detailed explanation-3: -A single full adder performs the addition of two one bit numbers and an input carry. But a Parallel Adder is a digital circuit capable of finding the arithmetic sum of two binary numbers that is greater than one bit in length by operating on corresponding pairs of bits in parallel.
Detailed explanation-4: -Serial binary adder. The serial binary adder or bit-serial adder is a digital circuit that performs binary addition bit by bit.
Detailed explanation-5: -There is a distinction between parallel adder vs serial adder. Both are binary adders, of course, since are used on bit-represented numbers. Parallel adder is a combinatorial circuit (not clocked, does not have any memory and feedback) adding every bit position of the operands in the same time.
