What is the definition of a parallel adder?
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.

What is a parallel adder?
The adders discussed in the previous section have been limited to adding single-digit binary numbers and carries. The largest sum that can be obtained using a full adder is 112. Parallel adders let us add multiple-digit numbers. If we place full adders in parallel, we can add two- or four-digit numbers or any other size desired. Figure 3-9 uses STANDARD SYMBOLS to show a parallel adder capable of adding two, two-digit binary numbers. In previous discussions we have depicted circuits with individual logic gates shown. Standard symbols (blocks) allow us to analyze circuits with inputs and outputs only. One standard symbol may actually contain many and various types of gates and circuits. The addend would be input on the A inputs (A2 = MSD, A1 = LSD), and the augend input on the B inputs (B2 = MSD, B1 = LSD). For this explanation we will assume there is no input to C0 (carry from a previous circuit). Figure 3-9. -Parallel binary adder. Now let's add some two-digit numbers. To add 102 (addend) and 012 (augend), assume there are numbers at the appropriate inputs. The addend inputs will be 1 on A2 and 0 on A1. The augend inputs will be 0 on B2 and 1 on B1. Working from right to left, as we do in normal addition, let's calculate the outputs of each full adder. With A1 at 0 and B1 at 1, the output of adder 1 will be a sum (S1) of 1 with no carry (C1). Since A2 is 1 and B2 is 0, we have a sum (S2) of 1 with no carry (C2) from adder 1. To determine the sum, read the outputs (C2, S 2, and S1) from left to right. In this case, C2 = 0, S2 = 1, and S1 = 1. The sum, then, of 102 and 012 is 0112 or 112. To add 112 and 012, assume one number is applied to A1 and A2, and the other to B1 and B2, as shown in figure 3-10. Adder 1 produces a sum (S1) of 0 and a carry (C1) of 1. Adder 2 gives us a sum (S2)
How does microprocessor add two numbers?
This is done by a combination of AND and OR circuits. Do some reading on "half adder" and "full adder" to get an introduction of how these circuits work. For example here: http://en.wikipedia.org/wiki/Adder_(electronics)In a real computer, in the simplest case two integers, each consisting of several bits, are added; this requires several half adders and full adders to be connected, one after the other.The actual computer circuits are more complicated than that, because of a need for speed. Also, the addition of "real numbers" (basically, numbers in scientific notation), often used on computers, is much more complicated than the addition of integers.This is done by a combination of AND and OR circuits.

How many full adder would be required to add two binary number each representing decimal number up through 1000 inbase ten?
Assuming the numbers to be added are positive only, 10 full adders are needed. If handling negative numbers by 2's complement, 11 adders will be needed.

Advantages of fast adder over parallel binary 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
Define half adder and full adder?
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.
