Narrated PowerPoint Presentation
Social, Cultural, and Ethical Issues
For your Final Project, you will create a PowerPoint presentation based on a topic from your current field of study. Since this is a fully online course and we do not meet in person in a traditional classroom setting, you will need to narrate this presentation so it can be viewed electronically.
To assist in the completion of your Final Project, some of the required pieces are included in this course as Milestones. These Milestones are completed throughout the course by the student and the instructor will provide feedback for each Milestone, in order to help the student better the overall quality of their project. See below where the milestones align with the Final Project requirements.
Topic:
Choose a social, cultural, or ethical issue related to your current major or field of study. Chose ONE area to focus on. For example, you cannot talk about ethics in healthcare, public safety, or IT in general. You would need to pick a single ethical issue to discuss and not just ethics in general. (Discussion 2)
Research:
Conduct a search using both internet and library database resources. You must use at least 3 sources, one of which must be from the library database. Keep track of these sources! You will need to include a reference slide at the end of your presentation. (Milestone 4)
Content:
Create a NARRATED PowerPoint presentation that contains between 12 to 18 slides. You must add your voice using the narration feature in PPT. Include the following:
Title Slide (1 slide) – includes your name and the presentation title.
Introduction Slide (1 slide) – should be something catchy and explain why this issue is important.
Body/Content Slides (8-14 slides) – must be interesting, well organized, and presented clearly. Slides should not contain full sentences/paragraphs.
Summary Slide (1 slide) – may also include a way for others to get involved, help, or get more information.
Reference Slide (1 slide) – must be in APA style and be a minimum of 3 resources. When including hyperlinks in the reference list, they must be hyperlinked. (Milestone 4)
PowerPoint Elements:
Include the following PowerPoint elements:
Apply a single theme or design template.
Apply a transition to each slide.
Do NOT use animation.
Provide at least one hyperlink to a video or useful online article, this does not include hyperlinks in citation/reference slide.
Use at least 5 open or royalty free images, cite the image on the bottom of the slide where the image exists (Milestone 6)
Use smart art at least one time.
Include an original graph, copied and pasted from Excel (do not include it as a picture, be sure to copy and paste from Excel). (Milestone 5)
Include a footer on each slide with the slide number and your last name.
Narration:
To earn full points, your presentation must be narrated. Do NOT read word for word from your slides. Slides should only contain bulleted information, but full sentences should be spoken. The narration audio should start automatically when you start the slideshow and should continue through the entire presentation.
Submission:
Please upload your completed PowerPoint project.

Compare and contrast digital evidence and non-digital evidence.
Provide three examples of how they are similar and three examples of how they are different. You must use the provided course materials for at least one of the examples. Provide a scenario in which additional investigation and non-digital evidence can be used to corroborate or refute digital evidence findings. Describe search warrants and how they can be used to obtain digital evidence by specifically answering each of the following questions:

Discuss how a search warrant can be used to obtain digital evidence
Explain how the Plain View Doctrine and Exigent Circumstances may apply to digital evidence.
Be sure to address what the Plain View Doctrine is and the three requirements an officer must fulfill if they are to successfully claim they were operating under the Plain View Doctrine
Describe a scenario in which an officer may claim the plain view applies to digital evidence—what might be an applicable counter argument be in court?
Explain what the exigent circumstances doctrine is and the category of circumstances that qualify as exigent circumstances under the doctrine.  Describe a scenario in which an officer may claim that the exigent circumstances doctrine applies to digital evidence—what might be an applicable counter argument be in court? Format Requirements:
Assignment must be double spaced, 11 or 12 pt font and 1” margins all around.
All APA 7th edition format requirements must be followed (cover page, in text citations, reference page). Refer to the APA information found in Content -> Course Overview -> Course Resources.
You must have resources to support your thoughts/opinions/information.  These must be cited both in text as well as at the end of the document. Your paper should not contain direct quotes, sourced material must be paraphrased. Course Outcome:
distinguish between digital forensics and forensic science to effectively analyze digital evidence and operate within the constitutional and case law parameters of the criminal justice system

As an IT specialist, one of your responsibilities it to develop a disaster recovery plan (DRP) for the organization in case of an emergency. Last year, there was a devastating fire at your place of business that took out the local server room and required the organization to move to a different building. Fortunately, due to good business continuity planning, the backup database was at another location; however, the team struggled with backup tools, processes, and policies when it came to supporting newfound remote employees. Now, your IT manager has asked you to prepare a DRP so everyone can be ready in case of a future emergency. Your manager has asked you to write a 1,050- to 1,400-word disaster recovery plan in a Word document. Include the following in your plan:
Identify 2 tools used for backup purposes that would support business continuity to ensure that the data can be accessed during the disaster.
Explain who is responsible for the backup. How often should data be backed up?
How will the data be protected while at rest? What security requirements will be necessary?
With respect to disaster recovery, explain how quickly the primary database should be restored. Why?
Explain how employees would access the backup database during business continuity efforts. Since the former office space is inaccessible, explain where the employees would work. What communication methods would be used? Outline the major components of a backup storage policy to include data at rest. Consider the steps you took in the week’s labs to support your outline. Cite at least 2 resources to support your assignment. Format your citations according to APA guidelines.

Question 1 : 25 points
A valid Red-Black tree should possess the following properties:
1. Every node is either red or black.
2. The root is black.
3. Every leaf is NULL and black.
4. If a node is red, then both its children are black.
5. All paths from a node x to any leaf have same number of black nodes in between (i.e.,
their Black-Height(x) is the same)
After insertion of a new key x to the tree, properties 3 and 5 may be violated causing the
tree to be become unbalanced. These violations can be overcome by rotating the tree around
certain nodes and updating their colors, as described in the slides.
(a) [10 points] Consider the Red-Black Tree given above. Insert the key 36 into it. Which
cases from the slides are you going to encounter? What rotations would you need to over-
come these problematic cases? What will the final tree look like? Explain your answer.
(Note: You must show the final state in picture and also explain which violation caused
you to use which rotation on which node as your progressed through the rebalancing of the
tree)
(b) [10 points] Asymptotic cost of inserting a new key to a red-black tree is O(log n). Why?
Explain your answer by showing the math.
(c) [5 points] Where would you use red-black trees? Why?
Question 2 : 25 points
Answer the following questions about graphs.
(a) [7 points] What is the maximum number of edges that can exist in an undirected graph?
What is the maximum number of edges that can exist in a digraph (a.k.a., directed graph)?
Explain how you came up with the answer in both cases.
(b) [8 points] Given a digraph G, its inverse GT is defined as digraph where all the edges of
the original graph are inverted. That is, ∀ (u, v) ∈ G.E, ∃ (v, u) ∈ GT .E. Describe a
non-empty digraph G such that G = GT .
(c) [10 points] A strongly connected component (SCC) of a digraph G is a maximal set
of vertices C ⊆ V such that for each pair of vertices, we have both u ↝ v and v ↝ u; that
is, vertices u and v are mutually reachable from one another.
One algorithm to calculate SCCs in a graph uses DFS as a subroutine twice; once on G and
once on GT . This is known as Kosaraju’s Two-Pass algorithm. Explain the intuition be-
hind how the DFS subroutine is able to help the algorithm discover the SCCs of a digraph.
(Hint: Don’t overthink it. This question can be answered in 3-4 sentences. Try to be
precise)
Question 3 : 20 points
The Computer Science program at Drexel University has a very complex course structure. As
you already know, certain courses are prerequisites for others. For example, you cannot take
CS260 before you take CS265 as the latter is a prerequisite for the former. For some reason, the
department has called upon you to help them figure out certain intricacies about the structure
of the program they themselves designed.
(a) [10 points] Is there any sequence of course that is not possible to take due to its, possibly,
unreasonable prerequisite requirements? Specify a graph algorithm, in plain English bullet
points, to answer this question by considering the following questions.
ˆ What will be the input to your algorithm? What will be the nodes and edges of your
graph?
ˆ How do you determine whether such an forbidden sequence exists?
ˆ What is the time complexity of your algorithm?
(b) [10 points] Assuming that a forbidden sequence of the form mentioned in part (a) doesn’t
exist, specify an algorithm, in plain English bullet points, that will output a permissible sequence of courses for a student to follow. Also, analyse your algorithm’s time complexity.
Question 4 : 30 points
Consider your path to success, which is pretty much like climbing a ladder. Very frequently in
life, as it is strictly the case for this problem, there are two choices in front of you: you either
step to the next step of the ladder, or skip the middle one and step on the second step. And
each step comes with a certain level of success (or failure), which is quantified by an integer
for this problem.
More formally, you are given an array of integers that represents the ladder and the values
stored in the array represents the contribution of landing on this step to your success.
Considering the costs of each step of the ladder, you are expected to suggest a strategy (i.e.,
an algorithm) that will provide the optimal steps to be taken to maximize the success by the
time you reach the pinnacle of your career.
(Disclaimer: once they reach the pinnacle, human beings either die and conclude their success
story in dust, or fall from there before they die and still end their story in dust!!! Moral of the
story: Success in career shouldn’t be the end goal…)
(a) [15 points] Suggest an algorithm for this problem (in bullet points) that utilizes binary
trees as part of its solution. Explain the runtime of your algorithm.
(b) [15 points] Suggest a more efficient algorithm that uses graphs instead of binary trees.
explain the runtime of your algorithm.
