• Follow each step carefully and make sure everything works before taking screenshots
• Use (my last name in naming) (webapp / screenshot files)

Lab 08:

• Create a web page that says “this is Lab #5 Submission”
• Screenshot showing UserABC accessing the page
• Screenshot proving the server has NO public IP
• Screenshot of the Application Proxy configuration

Lab 09:

• Screenshot from local (127.0.0.1:5000)

• Screenshot from VM (IP visible)
• Screenshot from Container (IP visible)

Important:

• The URL or IP must be clearly visible in every screenshot
• If theres any issue, stop and tell me before continuing

Software:

Software is the programs or apps that tell a computer what to do.

Example: Games, browsers, MS Word.

Hardware:

Hardware is the physical parts of a computer that you can touch.

Example: Keyboard, mouse, monitor, CPU.

Easy way to remember:

Hardware = you can touch it

Software = you cannot touch it

Hi i need help with 2 parts of my paper i did one assignment and was marked with feedback, could you help with the below

Unit 2

Description

The definition of your problem should now be completed, and you should be ready for the research phase. This is a key step in the research process and should result in meaningful, measurable, and useful information that you will use later for analysis purposes. Proper execution of your research plan will play a large role in the success of your project.

For this assignment, you will continue your work on the project with the focus on identifying a solution which can address the root cause of problem. You will first select the suited framework which will guide you to develop the solution. Then you will define the specifics of the solution and put it into a one sentence hypothesis statement. After carefully study both the problem statement and the hypothesis statement, you will extract a pair of important concepts reflected in the two statements. A research question can be formulated based on these two concepts. You can also use these two concepts qualified with the problem subject area as the search keywords to find some references which report the similar research works completed by other researchers. After evaluating these references you need to find out what are the main differences between those research works and the solution that you have proposed. All of these will be written into the corresponding sections of the Template of the Content of the Computer Science Problem-Solving Research Project Report document, will be presented as part of the submission for the week.

The following are the project deliverables:

• Update the Computer Science Problem-Solving Research Project Report document title page with a new date and project name.
• Update the previously completed sections based on instructor feedback.
• New Content for Week 2:
  • 2. Solution Identification
  • 2.1 Solution Framework
    • Based on the nature of the root cause of problem, discuss what computer science principles, models, concepts, algorithm, and platform, etc. should be applied in order to develop a proper solution to address the root cause of the problem. This part is considered as the theoretical foundation of the solution.
  • 2.2 Hypothesis Statement
    • Base of the Solution Framework, you will define the specifics of a solution that can be applied to resolve the root cause of the problem. Because this solution is only an assumed solution, it will be treated as a hypothesis at this stage of the research. You need formulate a one sentence hypothesis statement in a format of If the solution is implemented, then the root cause of the problem will be resolved.
    • For example, to solve the problem of the darkness in the classroom due to a sudden power outage in the evening, which is described by the problem statement of In the campus, all classrooms are now embedded in the darkness due to the sudden power outage, an assumed solution could have several possibilities: such as finding a electricity generator powered by either diesel or man-power, or finding some pre-charged batteries for lightening, etc. Therefore, the corresponding one sentence hypothesis statement can be written as: If we can find any of the following: an electricity generator powered by either diesel or man-power, or even some pre-charged batteries for lightening within the campus, we can effectively resume the classes. From this hypothesis statement we can see clearly what solution has been proposed in order to address or resolve the root cause of problem: the sudden power outage.
  • 2.3 Research Questions
    • Based on both the problem statement and the hypothesis statement, you should find out a pair of important concepts reflected in these two statements. Then you will treat one of the concepts as an Independent Variable, and the other concept as a Dependent Variable. Then use these two variables to formulate a research question in the format of How will the values of the Independent Variable changes impact the outcome of the Dependent Variable? This research question will become the guideline for designing research experiments in the nest step of the research process.
    • For example, we can easily extract two concepts: Type of Electricity Generator and Effectiveness of Electricity Generating through evaluating the problem statement and the hypothesis statement. We will use the Type of Electricity Generator as the Independent Variable as it can have at least three possible values. We will also use the Effectiveness of Electricity Generating as the Dependent Variable. Therefore, we can have the research question defined as: How will the values of the Type of Electricity Generator changes impact the outcome of the Effectiveness of Electricity Generating?
    • As you now can easily see that to answer this research question, all we need to do is to do the experiments by trying each type of electricity generator and measure the corresponding effectiveness of their electricity generating. That is the research question in fact has provided a clear guidance of how to design the research experiments.
  • 2.4.Related Works
    • By using the Independent Variable and Dependent Variable plus the subject area of the problem as the search keywords, you can easily find out some research works that are relevant in the publications. These publications should be used as the references for you to investigate what are the difference in details from the solution that you have chosen. You should select at least 5 such references, and make a short summary for each reference. The summary should point out the main technical feature, and the pros and cons of the research work, as well as the main difference from your solution.
      For example, if we use Electricity Generator or Effectiveness of Electricity Generating or Solution for Electricity Recovering during Sudden Power Outage as the search keywords to find the similar research works, we should be able find many references that are discuss the solution similar to what we are researching.
      After collecting the relevant references, all we have to do is to first classify them into categories, then make a summary on the main technical feature, the pros and cons of each category of solution, as well as the main difference between each category of solution and your solution. These summaries become the content of the section of Related Works
    • here were my teachers comments
    • Opportunities for improvement:
      > The Solution Framework is inadequate as no academic research was used to support potential solutions. The Solution Framework is also technically weak as Im unable to find where you describe at least two non-trivial potential solutions after the introduction of general concepts and principles. Edit to add in-depth description of potential solutions, supported by academic research, and complemented by figures.
      > The Solution Framework should end with an evaluation of the potential solutions and your selection of a recommended solution.
      > The Hypothesis Statement if overly vague and non-specific. Edit to state a clear and specific recommended solution for example, how to you recommend the company realize a micro service architecture?
      > The Related Works relies too heavily on non-academic references. Edit to replace non-academic with academic references. Focus more on technical content that helps identify potential solutions for your paper.
      > The table of content is out-of-date (e.g., two Problem Context and Background sections shown).
      > Work to address all previous comments.

    Afterwards i need help with unit 3 assignment

  DescriptionResearch has little value if there is no experiments to collect the data to help validating a solution to the original problem. The data gathered must be examined and properly analyzed to understand the results. Therefore, one of critical steps in any scientific research is to design and develop a set of suitable experiments.

  For this assignment, you will continue working on the project with the focus on the Research Methodology. You will define the relevant concepts and theoretical foundations that you will used in the design of the experiments to collect data in order to answer the research question, along with the requirements and detailed procedures of the experiments.

  The following are the project deliverables:

  • Update the Computer Science Problem-Solving Research Project Report document title page with a new date and project name.
  • Update the previously completed sections based on instructor feedback.
  • New Content for Week 3:
    • 3. Research Methodology
    • 3.1 Research Matters
      • Define everything including terminology, testing metrics, assumptions, system set up, or lab environment, etc. that may help the readers to understand the experiments that you are designing in order to collect data to answer the research question.
    • 3.2 Experiment Design
    • 3.2.1 Experiment Requirements
      • Define all the requirements and constraints the experiments must follow. Also explain the rationale of each requirement or constraint.
    • 3.2.2 Experiment Procedures
      • Define the detailed working procedures of the experiments. Using some graphic presentation such as some of UML Diagrams is highly recommended.

(1) Browse the short overviews of the projects. Read a bunch of them theyre really interesting.

But dont try to read them all unless you have a lot of spare time; there are lots!

(2) Pick a project for which you think at least three different Analytics models might have been

combined to create the solution.

(3) Think carefully and critically about what models might be used to create the solution, how they

would be combined, what specific data might be needed to use the models, how it might be

collected, and how often it might need to be refreshed and the models re-run. DO NOT find a

description online (or elsewhere) of what the company or organization actually did. I want

this project to be about your ideas, not about reading what someone else did.

(4) Write a short report describing your answers to (3).
