Please answer this question step-by-step so I can understand it. Thanks!

1. For Packet #8, name the protocols used at the Data Link, Network, Transport and Application Layers in this packet.
2. Which packets (#1-#14) contain the contents of the web page being downloaded? Your answer should include more than one packet.
3. What is the purpose of packet #11? What device sends it? Why is it sent?

This is for part (a):
