RSA decryption: You are given the following RSA values: n = 9797, e = 7, d = 4111. Some ciphertext was received: c = 7321. Based on that information, compute the plaintext message m. Show all your work along the way. No Use of AI please

(25 points) What are the use cases in which public key encryption would be useless? In light of what we discussed in class. would the internet be where it is today without the COIS-4370H-A-F01-2025FA-OSH Computer & Info Security Ords. City any sources you use. Remember to frame your answer in light of what was discussed in class.

2) You have learned in class the major steps that occur when a laptop requests a webpage after connecting to a network. In this assignment, you will apply that knowledge to another scenario: opening and playing a YouTube video that resides in Google's data-center infrastructure. Explain, in as much detail as you can, all the steps involved from your device's initial connection to the home/university network, to DNS resolution, routing across multiple networks, reaching Google's servers, and finally receiving the video data. To support your explanation, use tools such as ipconfig, nslookup, and tracert on your own computer, as well as any online IP-lookup tools of your choice. For each stage, include relevant information such as IP addresses, MAC addresses, router hops, and any other details you can gather. You are not expected to find every piece of information, but be as comprehensive as possible based on what you have learned in class, and justify your reasoning with screenshots from…
