A segmented memory has paged segments. Each virtual address has a 2-bit segment number, a 2-bit page number, and an 11-bit offset within the page. The main memory contains 32 KB, divided into 2-KB pages. Each segment is either read-only. read/write, or read/writelexecute. The page tables and protection are as follows: Segmento Segment 1 Read only Segment 2 Segment 3 Read/Write/Execute Read/Write Read only Virtual Page Virtual Page Virtual Page Virtual Page Page Frame Page Frame Page Frame Page Frame 0 0 0 On disk 0 13 1 1 1 1 5 Page Table not in main 2 On disk 2 9 2 2 memory 3 11 3 6 3 On disk 10 For each of the following accesses to virtual memory, tell what physical address is computed.If a fault occurs, tell which kind.
