### **STEP 1: Introduction to the Concept**
**Two-Dimensional Even Parity Scheme:**
In digital communications, parity bits are added to data for error detection.
- **Even parity** means the total number of 1s (including the parity bit) in each row and each column must be even.
- In a **two-dimensional scheme**, each row and each column has its own parity bit.
- If there’s a single bit error, the incorrect row and column parity bits will indicate the position of the error.
---
### **STEP 2: Examine Each Row for Parity Errors**
Let's check the parity for each row (sum of 1s should be even):
| Row | Data | Parity Bit | Total 1s (including parity) | Even? |
|-----|--------------|------------|----------------------------|-------|
| 1 | 1 1 0 0 | 0 (red) | 1+1+0+0+0 = 2 | Yes |
| 2 | 0 1 0 1 | 0 (red) | 0+1+0+1+0 = 2 | Yes |
| 3 | 1 0 0 1 | 1 (red) | 1+0+0+1+1 = 3 | **No**|
| 4 | 1 1 0 1 | 1 (red) | 1+1+0+1+1 = 4 | Yes |
**Conclusion:**
- **Row 3** has an error (parity is odd).
---
### **STEP 3: Examine Each Column for Parity Errors**
Now check each column (including the bottom red parity bit):
| Col | Data | Parity Bit | Total 1s (including parity) | Even? |
|-----|--------------|------------|----------------------------|-------|
| 1 | 1 0 1 1 | 1 (red) | 1+0+1+1+1 = 4 | Yes |
| 2 | 1 1 0 1 | 0 (red) | 1+1+0+1+0 = 3 | **No**|
| 3 | 0 0 0 0 | 0 (red) | 0+0+0+0+0 = 0 | Yes |
| 4 | 0 1 1 1 | 0 (red) | 0+1+1+1+0 = 3 | **No**|
**Conclusion:**
- **Column 2** and **Column 4** have parity errors.
---
### **STEP 4: Pinpoint the Error Bit**
- The error must be at the intersection of the row and column that failed parity.
- Rows: Row 3 failed parity.
- Columns: Column 2 and Column 4 both failed—since there’s only 1 bit error, let's check which one fits.
Check Row 3, Column 2: Value is **0**
Check Row 3, Column 4: Value is **1**
If error is in (3,2): flipping 0 to 1 makes Row 3: 1+1+0+1+1 = 4 (even), and Column 2: 1+1+1+1+0 = 4 (even).
If error is in (3,4): flipping 1 to 0 makes Row 3: 1+0+0+0+1 = 2 (even), Column 4: 0+1+0+0+0 = 1 (odd).
So, the error is at **Row 3, Column 2**.
---
### **STEP 5: Final Answer (Short and Clear)**
**Row number:** 3
**Column number:** 2
---
### **Summary of the Steps**
1. **Introduced the concept** of two-dimensional even parity for error detection.
2. **Checked each row** for parity errors: found error in Row 3.
3. **Checked each column** for parity errors: found errors in Columns 2 and 4.
4. **Pinpointed the error** by matching the intersection of the error row and columns; confirmed the error is at (3,2).
5. **Gave the final answer** in a concise form.
**Final Answer:**
The single-bit error is at row 3, column 2.
