Please prove the answer for all 4 questions blew by detailly, separatelywith some screenshot(which as a requirement in the question), and following the introduction, thank you very much.

Answer the following questions, based on the Wireshark:

1. List 3 different protocols that appear in the protocol column in the unfiltered packet-listing window in step 7:

"7. Type in http (without the quotes, and in lower case all protocol names are in lower case in Wireshark) into the display filter specification window at the top of the main Wireshark window. Then select Apply (to the right of where you entered http). This will cause only HTTP message to be displayed in the packet-listing window."

Support the answer with an appropriate screenshot from the computer.

2. How long did it take from when the HTTP GET message was sent until the HTTP OK reply was received? (By default, the value of the Time column in the packet-listing window is the amount of time, in seconds, since Wireshark tracing began. To display the Time field in time-of-day format, select the Wireshark View pull down menu, then select Time Display Format, then select Time-of-day.)

3. What is the Internet address of the gaia.cs.umass.edu? What is the Internet address of your computer? Support the answer with an appropriate screenshot from the computer.

4. Print the two HTTP messages (GET and OK) referred to in question 2 above. To do so, select Print from the Wireshark File command menu, and select the Selected Packet Only and Print as displayed radial buttons, and then click OK. "
