**Segmented Memory with Paged Segments: Understanding Virtual to Physical Address Translation**

In this problem, we examine a segmented memory system with paged segments. Each virtual address in this system consists of three parts:
- A 2-bit segment number
- A 2-bit page number
- An 11-bit offset within the page

The main memory is configured to contain 32 KB, divided into 2-KB pages. Each segment is defined with specific access permissions: read-only, read/execute, read/write, or read/write/execute. The provided page tables and protection levels for each segment are as follows:

**Segment Descriptions:**

1. **Segment 0 - Read Only**
- Virtual Page 0 maps to Physical Frame 9
- Virtual Page 1 maps to Physical Frame 3
- Virtual Page 2 is on disk
- Virtual Page 3 maps to Physical Frame 12

2. **Segment 1 - Read/Execute**
- Virtual Page 0 is on disk
- Virtual Page 1 maps to Physical Frame 15

3. **Segment 2 - Read/Write/Execute**
- Virtual Pages are currently not in page table

4. **Segment 3 - Read/Write**
- Virtual Page 0 maps to Physical Frame 14
- Virtual Page 1 maps to Physical Frame 6
- Virtual Page 2 is on disk

**Tasks:**

For each virtual memory access given, determine the physical address or fault type.

**Access Requests:**

1. Fetch data from Segment 0, Page 1, Offset 10
2. Fetch data from Segment 3, Page 1, Offset 2047
3. Store data in Segment 0, Page 3, Offset 4
4. Store data in Segment 2, Page 0, Offset 1
5. Store data in Segment 2, Page 2, Offset 0
6. Store data in Segment 3, Page 3, Offset 100
7. Branch to Segment 0, Page 1, Offset 1
8. Fetch data from Segment 3, Page 0, Offset 50
9. Fetch data from Segment 1, Page 0, Offset 5
10. Branch to Segment 1, Page 3, Offset 60

By analyzing these accesses, we can find out which
