#### Page Table Entries Calculation
To understand and implement efficient memory management systems, it is essential to determine the number of page table entries (PTEs) required for various combinations of virtual address size (n) and page size (P).
#### Example Problem
**Question: Determine the number of page table entries (PTEs) that are needed for the given combinations of virtual address size (n) and page size (P):**
\[ n = P = 2^p \]
| Virtual Address Size (n) | Page Size (P) | Number of PTEs |
| ------------------------ | ------------- | -------------- |
| 16 | 4K | |
| 16 | 8K | |
| 32 | 4K | |
| 32 | 8K | |
#### Steps to Calculate PTEs
1. **Identify the Virtual Address Size (n)**: This is typically a power of 2 (e.g., 16, 32).
2. **Select the Page Size (P)**: This is also typically a power of 2 (e.g., 4K, 8K).
3. **Calculate the Number of PTEs**:
\[
\text{Number of PTEs} = \frac{\text{Virtual Address Size}}{\text{Page Size}}
\]
#### Practical Task
To better understand this concept, let's work through an example.
**Example Calculation for a 16-bit Virtual Address and a 4K Page Size:**
- **Virtual Address Size (n)**: 16 bits
- **Page Size (P)**: 4K
\[ \text{Number of PTEs} = \frac{2^{16}}{4K} = 2^{16-12} = 2^4 = 16 \]
#### Interactive Section
**Part C:** Determine the number of page table entries (PTEs) in the third line. Express your answer as an integer.

```
**Part D:** Determine the number of page table entries (PTEs) in the fourth line. Express your answer as an integer.
```
Input: 8192
