1. What is DNS and how does it work? How does DNS help you connect to a web server like Amazon?
Answer
DNS, or domain name system, works by keeping a list of all the taken domain names and regulating them. DNA helps to connect to a web server such as Amazon translates domain names to IP addresses, so when the user types in, for example, amazon.com, they will be directed to the browser (via IP address) so that the browser can load the internet resources.
2. Include a screenshot of your message log in the DNS Simulation app in Activity 1.
(POGIL) Discuss why and how a list variable would be a better choice for storing the recipient’s multiple messages in the DNS simulation app.
Answer
A list variable would be a better choice for storing the recipients multiple messages in the DNS simulation app because as the app is used more and more messages are sent, they will need to be stored better and in an organized fashion if the messages amount increases significantly.
3. (POGIL) Include the pseudocode algorithms you developed for the sender and receiver to handle multiple messages to a recipient.
