Ch7 Mini-Case III: EUREKA Discussion (7.2; 7.3, 7.4) 200 words and 100 words respond

/in /by

 please i need this in 6 hours 

Chapter 7 Wired and Wireless LAN   

Purpose

To provide you the opportunity to research and illustrate the best practice recommendations for LAN design.

Directions

  1. Read the following scenario and answer the questions that follow in the discussion board area of class. Provide a thoughtful and informative response to the questions; you should be able to support your recommendations. Be sure to support your ideas with evidence gathered from reading the text or other outside sources. Be sure to give credit to the sources where you find evidence. Use an attribution like “According to the text,” or “According to Computer Weekly website” in your response. Your response should be a minimum of 200 words.
  2. Respond to at least one of your classmates’ posting. Your response should at a minimum of 100 words. A response like “I agree” or “Yes, you are correct” does not contribute to a robust discussion. Explain why you agree or disagree; share our own personal experience or knowledge gained from your readings.
  3. Submit this assignment in the Discussion Board. 

Scenario
Eureka is a telephone and Internet-based concierge services that specializes in obtaining things that are hard to find (e.g. Super Bowl tickets, first  edition books from the 1500s, Faberge eggs). It currently employs 60 staff members who collectively provide 24-hour coverage (over three shifts). They answer the phones and respond to requests entered on the Eureka! Web site. Much of their work is spent on the phone and on computers searching on the Internet. The company has just leased a new office building and is about to wire it. They have bids from different companies to install 

(1) 100-Base T network 

(2) Wi-Fi network What would you recommend? Why? In your proposal, include a diagram of our wired or wireless network.

Grading

This assignment is worth 50 points. I will grade your responses based on accuracy and completeness. Your initial posting should be at least 200 words and your response to at least one classmate should be at least 100 words. 

i have attached a picture and its the post you will be responding too with 100 words or you can see below to respond.

In the situation of the Mini-case III, the telephone and Internet-based concierge services named Eureka, needs to wire a new office. The company has the choice between a 100Base-T network and a Wi-Fi network. According to me, I would recommend the company to install a 100Base-T network. During this study, I will explain my choice.

First of all, my choice of this type of network is related to two main reasons. The first reason is the connection speed. According to the book in Chapter 7 p.188, the 100Base-T network supports data transfer rates up to 100 Mbps. According to Webopedia website, the 100Base-T network is 10 times faster than Ethernet and often referred to as “Fast Ethernet”. It’s important to mention that because Eureka is an internet-based company which employs 60 staff members who work a lot. The employees will need a fast connection to perform their work. However, it could be challenging to use a Wi-Fi network. Even though the wireless network is faster than the wired network, the 100Base-T network will be a better choice in this case because the Wi-Fi network would be overloaded due to the amount of work in the company.

Secondly, apart from the connection speed, I chose the 100Base-T network instead of the Wi-Fi network, because of security. We all know that security is very important for telephone and internet-based companies since they have customers’ personal information on file. If Eureka installs a wired network, all personal data will be stored and only the workers will have access to that. However, the Wi-Fi network is less secured. According to Lifewire website, signals from most wireless local area networks pass through exterior walls and into nearby streets or parking lots. In the Eureka situation, insecurity of the connection will be a constraint for the company.

  Definitely, installing a 100Base-T network instead of a Wi-Fi network will be advantageous for Eureka. Every employee will be reassured to do his job safely and efficiently. The company will not receive complaints from customers because workers will do their work on time.

Support Queue Case Study

/in /by

 Instructions

For this project, you will apply the CompTIA 6-Step Troubleshooting Process to explain how you would tackle Hudson Fisher Associates Help Desk Tickets. There are three groups of tickets, Level 1, Level 2, and Level 3. You will pick two tickets from each group.

As you prepare to analyze and hopefully solve these typical IT help desk tickets, keep in mind that for this course, it is more about the process and less about finding the “correct” answer. You may not always find an exact answer from the information given. The problems are structured to approximate what you will find in the workplace. Use a logical and repeatable process (e.g., the CompTIA 6-Step Troubleshooting Process) and eliminate the improbable as you work your way through each scenario.

CompTIA 6-Step Troubleshooting Process:

  1. Identify the problem.
  2. Establish a theory of probable cause.
  3. Evaluate the theory to determine the actual cause.
  4. Establish a plan of action to resolve the problem and implement the solution.
  5. Verify full system functionality and if applicable implement preventative measures.
  6. Document findings, actions, and outcomes.

How Will My Work Be Evaluated?

As you progress in your information technology and cybersecurity career, you may find yourself making presentations to customers, client audiences, and management. For this assignment, you should articulate your findings from the six support cases.

But the challenge you face is in expressing a technical solution to a nontechnical audience. Avoid jargon and acronyms. Find a way to relay your solution (and challenges) in language that your audience will find easily relatable.

Communicating in this manner will not always be easy. You may struggle to find the right analogy or metaphor. But if you can master the skill of summarizing your results and recommendations to management in an effective presentation, you will demonstrate how you use your technical knowledge to convey your ideas to others in a professional setting. You will also earn the respect and trust of your peers, your supervisor, and upper management as an effective communicator. You will be viewed as an employee ready for advancement.

The following evaluation criteria aligned to the competencies will be used to grade your assignment:

  • 1.1.1: Articulate the main idea and purpose of a communication.
  • 1.1.3: Present ideas in a clear, logical order appropriate to the task.
  • 1.3.3: Integrate appropriate credible sources to illustrate and validate ideas.
  • 2.1.1: Identify the issue or problem under consideration.
  • 2.3.1: State conclusions or solutions clearly and precisely.
  • 12.7.2: Explain the process of analyzing IT incidents.
  • 13.1.1: Create documentation appropriate to the stakeholder.

Your deliverable for the project is an annotated PowerPoint Presentation covering the following:

  • List of the six tickets you selected (two each from Level 1, Level 2, and Level 3)
  • One to two slides for each ticket, in which you:
    • State the problem.
    • Describe the steps taken to troubleshoot/analyze the problem.
    • Propose a brief resolution.
  • One summary slide: What did you find challenging or interesting about one or two of the support cases (opinion-based)?
  • One reference slide (two to six IEEE references). Include references for materials you consulted in TestOut or on the internet.

If you haven’t already done it last week, download the Support Queue Case Study Presentation Template to get started.

Delete the instructional text from the template before you submit.  

When you are finished, click “add a file” to upload your work, then click the Submit button.

just answer 1 question

/in /by

choose 1 question and answer it. (200 words)

use the pdf file chapter 1 to answer

  

1. What is encompassed in the question “why computer ethics?” In other words, what more specific questions are included in the broad question?

     – What is computer ethics? What does it mean?

     – Why do we have to learn ethics?

     – Is computer ethics important or not?

     – Is it connected to our course?

     – Is computer ethics helpful? 

2. Give a concise summary of Moor’s standard account of computer ethics.

     – Moor’s standard account of computer ethics is saying that when IT comes up a new possibilities for people’s action that is because Ethical issues arises around IT.

3. What is a policy vacuum? Give an example, and explain it using the standard account.

     – Policy vacuum means “no policy”. For example, A Benildean girl went to her school wearing slippers. At that time, the school accepts slippers then suddenly made a school policy of dress code. She wore slippers because there were no rules of not wearing slippers. She can be excused if her feet/s were injured.

     Using it in the standard account, the policy vacuum are filled when there are questions or conceptual muddle that needs to be solved or answered. 

4. What is a conceptual muddle, and how do they get in the way of filling policy vacuums? Illustrate with an example.

     By the word itself, muddle means mix-up, confusing, or jumble. Conceptual muddle gets in the way of filling policy vacuums because conceptual muddles are the questions that to be answered and be solved so they are like making the created policy change. For example, A man asked the IT department if he could access his email account to read his personal emails. The IT says “no” but with reconsiderations and depending on his request he can access his email account with a desired time and if it is business related. 

5. What is wrong with the standard account of computer ethics? Identify at least two criticisms, and explain.

     The problem with the standard account of computer ethics is the “newness”. In the book, “newness” may skew the kind of analysis that is done. 

6. What are the two tenets of the view referred to as “technological determinism”? What is the STS critique of each tenet?

     – “technology develops in isolation and according to its own logic – should be rejected outright” 

          = It does not follow a predetermined or “natural” order of development.

     – “technologies are adopted by societies or particular social groups, the adoption brings about – determines – social arrangements and patterns of social behavior”

          = When we say that technology determines society, we are forgetting that the technology has been socially shaped; social factors and forces have influenced the development and design of the technology. 

7. What is wrong with thinking of technology as merely material objects?

     In the statement “thinking of technology as merely material objects”, it sounds normal but it doesn’t look at the main idea why technologies are invented. 

     In the chapter 1 of Computer Ethics, about “Sociotechnical”, one of the lessons of STS, is not to think of technology as material objects. As sited in this chapter, that “Facebook users think of the site not just as a material object or piece of software, but as a “social” networking site”. 

8. What is a sociotechnical system?

     For me, sociotechnical system is a system that people should might know. It helps in our decision making and critical thinking. It helps us stretch our mind, ask questions that obviously want decent answers.    

     Written in the book of Computer Ethics, “sociotechnical systems perspective provides a richer account of situations in which ethical decisions are made, one that may help in articulating moral concerns as well as revealing additional avenues for addressing ethical questions and issues”.

9. Choose a familiar technology and describe its values?

     – Internet

          = helps users to reconnect with other people

          = to gather informations

          = to send files from other people

10. What is the difference between micro-level ethical issues and macro-level ethical issues?

         Micro-level ethical issues are for the individuals’choices and their behavior. 

         Macro-level ethical issues are for big groups that everyone can be affected.

11. Why is the study of ethics and technology needed? Why is the study of ethics, and IT in particular, needed?

     The study of ethics and technology is needed because:

          = Ethics -> In ethics, ethics gives us to explore our mind or to widen our mind, ask questions to the unknown, ask questions to the unjust, and etc.  It helps us to think more of cases that are somehow wrong and right. 

          = Technology -> We need technology. As we our world continues to grow on technologies, we began to be attached to the technologies we created. We are so attached that people can’t live without it. That is why Ethics is needed because Ethics is like the one stopping the evil deeds of an evil person using technology. 

     The study of ethics and IT in particular is needed because these IT people are mostly creating ethics. Reading some of the recent cases can actually relate some of your problems that can be solved under some of the circumstances.
