b. Using the above addresses as a guide, provide an example of a logical address (in hexadecimal) that results in a page fault. c. From what set of page frames will the LRU page-replacement algorithm choose in resolving a page fault?

b. 根据上面的虚拟地址，假设逻辑地址为0x1234，则对应的页号为0x12，由于页面表中没有页号为0x12的页表项对应的页框，因此会产生缺页中断(page fault)。

c. 当发生缺页中断时，LRU页面置换算法将从当前进程正在使用的页框集合中选择最近最久未使用的页面进行替换。根据页面表中给出的页框分配情况，当前进程正在使用的页框集合为{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}。因此，LRU页面置换算法将从这16个页面中选择最近最久未使用的页面进行替换，以便为新的页面分配一个页框。

3.Write a command to show the ip addresses that each network interface have.

On Linux or macOS, you can use the command `ifconfig` to display the IP addresses of all network interfaces. For example:

ifconfig

This will show information about all network interfaces, including their IP addresses.

On Windows, you can use the command `ipconfig` to display the IP addresses of all network interfaces. For example:

ipconfig

This will show information about all network interfaces, including their IP addresses.

Write a command to show the ip addresses that each network interface have.

On Linux, you can use the `ifconfig` command to display the IP addresses of all network interfaces.

Open the terminal and type the following command:

ifconfig

This will display the IP addresses for each network interface on your system.
