Use the following scenario to answer the next four questions: Dr. Deci reads about speculation that aggression in females is caused by higher exposure to testosterone while in utero. She decided to test this by examining twins. She recorded testosterone levels while in the womb using both female-female twin pairs and female-male twin pairs.  Dr. Deci then assessed aggression in all of the females at ages 10 and 18. Dr. Deci found no relationship between testosterone exposure and aggression levels.

What is the purpose of TTL in DNS records?

End-to-End Throughput Question: Overview. Consider the scenario shown below, with four different servers connected to four different clients over four three-hop paths. The four pairs share a common middle hop with a transmission capacity of R = 400 Mbps. The four links from the servers to the shared link have a transmission capacity of RS = 50 Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of RC = 20 Mbps. Answer the following five questions based on the scenario described above.

Which of the following network applications typically runs over UDP?

In the application layer protocol stack, which statement is true about user applications?

An October 27, 2023 article in the New York Times entitled “The Consequences of Elon Musk’s Ownership of X” begins as follows: When Elon Musk bought Twitter a year ago, he said he wanted to create what he called a “common digital town square.” “That said,” he wrote, “Twitter obviously cannot become a free-for-all hellscape.” A year later, according to study after study, Mr. Musk’s platform has become exactly that. Now rebranded as X, the site has experienced a surge in racist, antisemitic and other hateful speech. Under Mr. Musk’s watch, millions of people have been exposed to misinformation about climate change. Foreign governments and operatives — from Russia to China to Hamas — have spread divisive propaganda with little or no interference. It gets worse from there. After reading the article, you’ve become worried about Twitter/X’s stability and social responsibility when Elon Musk is the owner (and when the company’s CEO is a Penn State alumna, Linda Yaccarino). These thoughts, combined with your computer networking knowledge learned in IST 220 and throughout the rest of your education at Penn State, inspire you to create your own new Twitter alternative, Roar. While the basic functionality of your application will be similar to that offered by Twitter/X, you hope that yours will be more secure, reliable, and ethical. Basically, you want Roar to be a superior alternative to Twitter/X. You’ll be creating both a network application and an application-layer protocol to create the service. It is now time to answer the three big questions we’ve discussed throughout topic 2. Please answer the following questions in numbered paragraphs. Would you recommend a client-server architecture, or a peer-to-peer architecture? Why? (2 pts) Would you recommend using TCP, or UDP? Why? (2 pts) Would you recommend using an open protocol, or a closed/proprietary protocol? Why? (2 pts)
