Lab Analysis

1. Scott asks you to explain the main operational difference between TCP and UDP. How does this difference affect which services use TCP or UDP?

2. Ann wants to know how ports open and close. She also wants to know what effect firewalls have on the actual opening and closing of ports. Can you help her?

3. Harrison wants you to give him a quick rundown of the TCP three-way handshake. Can you quickly summarize it for him?

4. Meir, while capturing packets with Wireshark, pings one of the other computers on his network. He examines the output of the capture and finds the section relating to the ping activity. What is the underlying protocol you would expect Meir to observe?
