I’m working on a computer systems writing question and need guidance to help me learn.

1. For the following Paging configuration discuss what must be done to ensure a processes address space is not violated.

2. How many memory references would it take to fetch a word from memory if the process requires 80 G of memory and the system has 8 G of physical memory?  Page size is 2k.

3. Describe how a page fault is handled?

4. Given the page reference string  1 2 3 2 1 5 2 4 5 3 2 1 5 2 3 4 5

Show the time sequence of memory that has 3 frames for FIFO, Optimal, LRU, and Second Chance.  Indicate for each time whether a page fault occurred.  How many page faults occurred for each algorithm?

5. Repeat the question above for 4 frames.

Using the given design pattern, select an example that can be used for an Observer and a Singleton design pattern.

I’ve provided the design pattern from my previous work, and now need to use the observer and singleton design patterns to create java classes with these following classes. You can add more details if needed

You should have the following classes:

1. An abstract Subject class
2. A concrete Subject class which is ALSO a Singleton (based on assignment)
3. A Observer interface
4. A concrete Observer class (based on assignment)

And finally, the code that shows how the concrete observer attaches to the Subject

The code can be saved via java or .txt thank you

Competency

In this project, you will demonstrate your mastery of the following competency:

• Analyze user problems to inform user-centered design solutions

Scenario

The IT department at MYU (MY University) is considering a new student portal. The current portal has been in use for a number of years, and learners are encountering numerous issues regarding usability. The university has decided to start fresh. Therefore, it has conducted a task analysis of what students have to do to register for a class within the current portal. As a usability engineer, you have been asked to analyze the issues that exist within the user interface and task analysis, then write a report to be shared with university officials. Within this report, you will provide recommendations and create user personas. Additionally, you have been asked to create a paper prototype that addresses issues identified within the task analysis and conduct an observation of someone using your prototype.

Directions

In order to create your 2- to 3-page report, you will have to experience the registration process using the demonstration system and Student Portal Task Analysis provided in the Supporting Materials section. Your project also involves an in-person observation of someone using the paper prototype you create in response to the issues you identify within the student portal. Plan accordingly; you will need time to recruit your subject, complete the observation, and document the experience.

Within your report, you must:

• Identify user issues within the task analysis that impact usability
• Provide written recommendations, informed by user-centered design, that could be implemented to improve usability. Your recommendations should address:
  • Effectiveness
  • Efficiency
  • Utility
  • Learnability
  • Memorability
• Create three user personas based on the user profiles and task analysis. These personas will represent information regarding user needs (register for class, complete and turn in homework, access portals appropriate to major, complete assigned readings, petition to graduate), experiences, and behaviors when interacting with the student portal. For each persona, identify the user’s:
  • Age range
  • Familiarity or comfort level with technology
  • Time of access (e.g., early morning, late at night)
  • Method of access (e.g., PC, phone)

Additionally, you must:

• Construct a paper prototype that resolves issues found in the task analysis. The paper prototype is a paper representation of the design that shows the tasks and subtasks the user must accomplish to complete the intended goal. Users are able to “interact” by pointing to a representation of a button, menu, or other options available through the interface. The designer (you) would present another paper representation showing the screen corresponding to the chosen option. Your prototype must address:
  • Navigation issues that users encounter
  • Language issues within the portal
  • Issues that users cannot recover from in the current portal
  • The needs of all three personas
• Conduct an observation of someone using your paper prototype. You may recruit a coworker, family member, or friend. You will need to conduct this observation in person. During this observation, you will provide specific guidance to lead the user through the prototype while documenting their experience and your observations using the Prototype Observation Template provided in the Supporting Materials section. Plan accordingly; you will need time to recruit your subject, complete the observation, and document the experience.

What to Submit

To complete this project, you must submit the following:

Recommendation Report
This 2- to 3-page report includes:

• The identified issues within the task analysis
• Your recommendations to improve the user experience
• User personas based on the user profiles and task analysis

Paper Prototype
The paper prototype is a paper representation of the design that shows the tasks and subtasks the user must accomplish to complete the intended goal. Users are able to “interact” by pointing to a representation of a button, menu, or other options available through the interface. The designer (you) would present another paper representation showing the screen corresponding to the chosen option. Since this is a paper prototype, you may need to submit scanned images or photos of your prototype.

Prototype Observation Documentation
Document the experience of the user and your observations using the Prototype Observation Template provided in the Supporting Materials section.

Competency

In this project, you will demonstrate your mastery of the following competencies:

Analyze the design of a risk mitigation plan for its inclusion of best practices in the field

Identify legal and ethical considerations in risk analysis and mitigation within an information technology environment

• Scenario
• You are a risk management consultant and have been contacted by the chief information officer (CIO) of Workers Werks Credit Union (WWCU), a mid-size but growing credit union, to conduct an evaluation of its current IT cybersecurity risk management plan. Data privacy is a big concern in the banking sectors, and the CIO is concerned that WWCU’s current plan is outdated and has significant weaknesses.

In your conversation with the CIO, you gather the following information about the situation:

Current plan: The credit union adopted the current cybersecurity risk plan three years ago, but the CIO is concerned about possible gaps in the plan and would like to update it.

Workforce: The credit union has experienced significant revenue growth, and the number of employees with access to its IT infrastructure has grown exponentially in the last five years.

WWCU now has nearly 1,000 users with different levels of access to its central database.

• Strategy: The credit union is looking to expand into new markets in the coming year and will need to make significant changes to its IT infrastructure.

Compliance: The CIO is concerned not only about legal compliance but also ethical issues related to the protection of personally identifiable information (PII) of its customers. The company has set these priorities related to legal and ethical compliance:

• Address the current legal environment (domestic and international)

Anticipate emerging issues

Meet industry ethical standards (e.g., https://www.sans.org/security-resources/

• Match best practices for risk planning within the industry
• Directions

Risk Analysis Report
The CIO is asking you to prepare a 3–4 page report that evaluates the company’s current IT Security Risk Management Plan, linked in the Supporting Materials section.

• The report should contain the following:

Scope: Evaluate the scope and comprehensiveness of the current plan.

How does the plan describe its objectives?

• How does the plan balance risk and cost?
• In what ways does the plan cover the business objectives end to end?
• How does the plan address all stakeholders who could be impacted by a cybersecurity attack?

Risk: Determine how the current plan identifies risks.

• How does the plan identify the risks, vulnerabilities, and threats that could impact mission-critical business functions and processes?

How does the plan identify industry-related risks (internal and external)?

Impact: Analyze how the identified risks might impact the organization’s assets.

How does the plan identify key assets and activities that need to be protected?

How does the plan estimate the financial impact of losses?

How does the plan address business continuity and asset replacement?

Mitigation: Evaluate the current plan’s mitigation recommendations.

1. How effectively does the plan translate the risk assessment into a risk mitigation plan?

How does the plan prioritize risk elements?

Legal Compliance: Assess how the plan addresses legal considerations.

1. Non-Compliance: Determine how the plan anticipates the implications of non-compliance.
2. Ethical Considerations: Assess how the plan aligns with current ethical codes within the cybersecurity field.

6. topic is to write about COVID 19 experience you have to first plan what to write. Then make a rough draft. Then revise it. Then u edit your draft. Then proof reading

The articles MUST cover new technology, the latest information of the subject. I don’t want you to tell me how a carburetor works, I want you summarize an article that covers the latest development in aircraft carburetors. I don’t want to know about the newest aircraft from Boeing, I want to know why the engine on it is the newest and best one out there. Do not use the “How Stuff Works” or similar websites   as your source.
