Question
**Title: Parallel Adder and Binary Addition**

**Description:**

This educational resource explains how to perform the complete sum and carry for given 5-bit binary numbers using a parallel adder circuit. The example illustrates adding the binary numbers 11001 and 10001 using five full adder (FA) units. Each unit processes a pair of bits from the binary numbers and any carry from the previous lower unit.

**Binary Addition:**

- **Numbers to be Added:**
  \[
  11001
  +10001
  \]

**Circuit Explanation:**

The diagram consists of five full adders (FA1 to FA5) arranged in a sequence from right to left, corresponding to the least significant bit to the most significant bit. Each full adder is labeled to accept inputs \(A\), \(B\), and a carry-in \(C_{\text{in}}\), while producing a carry-out \(C_{\text{out}}\) and sum \(\Sigma\).

**Full Adder Details:**

1. **FA1:** 
   - Inputs the least significant bits and initial carry-in (usually zero).
   - Outputs the sum and a carry-out to the next full adder.
   
2. **FA2 to FA5:** 
   - Each accepts its respective bit from the numbers, the previous adder's carry-out as carry-in.
   - Continues producing a sum and carry-out passed to the next adder.

**Carry and Sum Propagation:**

- The sum output from each full adder becomes part of the final binary sum.
- Carry-outs are propagated left, feeding as carry-ins to the next significant bit's adder.

**Verification:**

- Perform the addition manually (longhand) to verify the result matches the circuit's computation.

**Conclusion:**

Through this structured approach, you can confirm the addition of binary numbers and understand the logical operation of parallel adders in digital circuits.
