Importance of Information Systems

Question a) What are QoS metrics? (Do not just spell the acronym.)  b) Why are QoS metrics important? Question a) Distinguish between rated speed and throughput. b) Distinguish between individual and aggregate throughput. c) You are working at an access point with 20 older people. Three are doing a download at the same time you are. The rest are looking at their screens or sipping coffee. The access point you share has a rated speed of 150 Mbps and provides a throughput of 100 Mbps. How much speed can you expect on average for a download? (Answer 25mbps) d) In a coffee shop, there are 10 people sharing an access point with a rated speed of 2 Gbps. The throughput is half the rated speed. Several people are downloading. Each is getting an average of 100 Mbps. How many people are using the Internet at that moment Question a) Distinguish between dedicated and multiplexed transmission links. b) If 100 conversations averaging 50 Mbps are multiplexed on a transmission line, will the required transmission line capacity be less than 5 Gbps, equal to 5 Gbps, or more than Gbps? c) What is the business benefit of multiplexing? Thought Questions 3-1 and 3-3  3:1 Your home is connected to the internet. You get to create SLAs that the ISP must follow. Being reasonable, write SLAs you would like to have for the following things.a) Write an SLA for speed. b) Write an SLA for availability c) Write an SLA for latency. Do not just say what each SLA should include. Actually, write the SLAs as the ISP would write them in the form of specific guarantees. Failure to do this will result in a substantial grading penalty.

I want to use the Comcast email service for effective emailing communication with my clients, business partners, and associates. I want to configure my Comcast email account on my computer system, but I am failing to complete the configuration process. I have configured so many email accounts, but I am going to set up a Comcast email account for the first time. Even I have good technical expertise for the configuration process of the Comcast email account. I am not sure about the Comcast email settings. And I am getting problems to configure the Comcast email account in the appropriate ways. Due to insufficient technical skills, I am missing something very simple for the configuration process of Comcast email accounts. Could anyone share the easy tips to configure the Comcast email account on my computer system?

Imagine that you are the Information Systems Security Specialist for a medium-sized federal government contractor. The Chief Security Officer (CSO) is worried that the organization’s current methods of access control are no longer sufficient. In order to evaluate the different methods of access control, the CSO requested that you research: mandatory access control (MAC), discretionary access control (DAC). and role-based access control (RBAC). Then, prepare a report addressing the positive and negative aspects of each access control method. This information will be presented to the Board of Directors at their next meeting. Further, the CSO would like your help in determining the best access control method for the organization. Write a three to five-page paper in which you:  Explain in your own words the elements of the following methods of access control: a. Mandatory access control (MAC) b. Discretionary access control (DAC) c. Role-based access control (RBAC) 2. Compare and contrast the positive and negative aspects of employing a MAC. DAC. and RBA, 3. Suggest methods to mitigate the negative aspects of MAC, DAC. and RBAC. 4. Evaluate the use of MAC, DAC, and RBAC methods in the organization and recommend the best method for the organization. Provide a rationale for your response. 5. Speculate on the foreseen challenge(s) when the organization applies the method you chose. Suggest a strategy to address such a challenge(s). 6.
