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.
Rowan Atkinson, who plays Mr. Bean, and Hugh Laurie, who plays House, both starred in a British comedies called Black-Adder II, Black-Adder III, and Black-Adder Goes Forth.
they are integrated in the calculators
You use a look ahead carry adder to reduce the propagation delay effects caused by the ripple carry that would otherwise be used. With ripple carry, each stage is dependent on the preceding stage, and this is cumulative. With look ahead carry, the carries are computed in parallel, speeding up the overall process.
Wikipedia has one under "Adder". I apologize, it is not easy to draw such things here.
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.
1.serial adder add bits serially but parallel adder add bits at the same time . 2.serial adder depends on previous outputs but parallel adder does not depends on previous outputs . 3.parallel adder takes less time to execute compared to serial adder.

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
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.
A parallel adder is a binary adder that can possibly form sum and carry the outputs for addend and augend words that operate on corresponding pairs addend and augend bits in parallel.
A binary parallel adder is a digital function that produces arithmetic sum of two binary numbers in parallel. It consists of full-adder combinational arrangement thus, the output carry from one full adder connected to the input carry of next full- adder.

Carry select adder is used to select the carry during addition of two numbers. If those numbers are of 64 bits, then we call it as a 64 bit carry select adder.
A 4bit parallel adder can be implemented by connecting four (4) full adders in parallel that will count from zero to fifteen.

The parallel adder which we use in the digital circuits ,the carry output of each full adder stage is connected to the carry input of the next higher order stage.therefore,the sum and carry outputs of any stage cannot be produced until the input carry occurs; This leads to a time delay in the addition process.This delay is known as carry propagation delay. to the second question the propagation delay can be avoided in the binary parallel adder with the help of look ahead carry generator .............................................................................................................................
