Need help to explain using macbook air by typing traceroute www.kean.edu explain the qustion below

To ping not only the connected Server but also the intermediate nodes, at the command prompt, type traceroute xxx.xxx.xxx.xxx (use traceroute in Mac OS). Note that the xxx.xxx.xxx.xxx is the URL or IP address of the targeted server. Here, we will traceroute www.kean.edu. 1. Observe the information shown. How many actual intermediate hops? 2. Which intermediate node takes the longest time? 3. Repeat step 4 four more times. Comparing the routes, do you see any difference in the intermediate nodes? If yes, can you think of any reason why that happens? 4. Using the intermediate notes in the 5 routes to draw the network topology.
