This is a comprehensive review for all chapters in the textbook. Please address the questions and then submit. You will need to ensure to use proper APA citations with any content that is not your own work. Each question should have a minimum of 600 words.

1. Suppose that you are employed as a data mining consultant for an Internet search engine company. Describe how data mining can help the company by giving specific examples of how techniques, such as clustering, classification, association rule mining, and anomaly detection can be applied

2.Identify at least two advantages and two disadvantages of using color to visually represent information.

3.Consider a group of documents that has been selected from a much larger set of diverse documents so that the selected documents are as dissimilar from one another as possible. If we consider documents that are not highly related (connected, similar) to one another as being anomalous, then all of the documents that we have selected might be classified as anomalies. Is it possible for a data set to consist only of anomalous objects or is this an abuse of the terminology?

4.For sparse data, discuss why considering only the presence of non-zero values might give a more accurate view of the objects than considering the actual magnitudes of values. When would such an approach not be desirable?

5.Assume that all documents have been normalized to have unit length of 1. What is the “shape” of a cluster that consists of all documents whose cosine similarity to a centroid is greater than some specified constant? In other words, cos(d, c) ≥ δ, where 0 < δ ≤ 1.

Provide a reflection of at least 500 words (or 2 pages double spaced) of how the knowledge, skills, or theories of this course have been applied, or could be applied, in a practical manner to your current work environment. If you are not currently working, share times when you have or could observe these theories and knowledge could be applied to an employment opportunity in your field of study. (InfoTech in a Global Economy).

Requirements:

Provide a 500 word (or 2 pages double spaced) minimum reflection.

Use of proper APA formatting and citations. If supporting evidence from outside resources is used those must be properly cited.

Share a personal connection that identifies specific knowledge and theories from this course(InfoTech in a Global Economy).

Demonstrate a connection to your current work environment. If you are not employed, demonstrate a connection to your desired work environment. 

You should not, provide an overview of the assignments assigned in the course. The assignment asks that you reflect how the knowledge and skills obtained through meeting course objectives were applied or could be applied in the workplace. 

The Term Project assignment offers the opportunity to explore/research a specific topic in computer systems in-depth and present your findings in the form of a written report.  Your term project must be 5-10 pages not including a cover page and reference section of at least 5 peer- reviewed articles.

This assignment must follow APA style, 12 Font, and Double Spaced.

The topic selected should include a comprehensive assessment of the basics of Computers, the role in which they play and the needs of an organization and/or person as it relates to your selected topic. 

1. Describe systems at risk, data breaches, the need for disaster recovery, and how data centers fit into this equation. 

Exploit the vulnerable program (vulnerable.c) to obtain a shell. The vulnerable program and sample exploit (you need to edit the exploit to make it work) are in the Assignments folder which in turn is in the Documents folder in the TritonApps lab environment. Provide commands and the screenshots of the outputs to illustrate your exploit. [10 pts]

Answer the following questions related to the exploit:

a. Which function and statement in the program is the major cause of the vulnerability? Why? [10 pts]

b. What address are you using to overwrite the return address? How did you obtain this address? [10 pts]

c. Draw a figure of the overflow string that leads to a successful buffer overflow attack and a shell. The figure should highlight the important addresses and contents. [10 pts]

d. What offset worked for your exploit? How did you find the offset? [10 pts]

The bonds between siblings are among the strongest. May-Lee Chai describes the relationship between two sisters in her short story, “Saving Sourdi.” 

After reading “Saving Sourdi,” discuss the following questions in 3–5 paragraphs:

1. The story begins with a strong revealing statement from Nea, the narrator. How do you think Nea feels about her sister Sourdi based on this information? How does what happens at the beginning of the story foreshadow what happens later?
2. This story is told from Nea’s point of view. How do you think the story would change if it were told from Sourdi’s point of view? Do you feel closer to the character than you would if this story were told in third person?
3. Nea briefly mentions an experience she and Sourdi had in a minefield when they were younger. What impact do you think this had on the relationship between the sisters?
4. Nea’s family is not originally from the United States. What are some clues the author gives to describe the origin of their ethnicity? Give 2 examples of characters who say things that are racially offensive, and discuss how this makes you feel about those characters. Can you relate to these experiences?
5. How does the author describe Duke and Mr. Chhay? Do you get a sense of who these characters are based on these descriptions?
6. As the story progresses, how does the relationship between Nea and Sourdi change? Why do you think it changes?
7. What does the mother value, based on how reaction to updates she receives from Sourdi? Why do you think she might feel this way?

Conduct your own social engineering experiments.

1) While at a restaurant, convenience store, bank, place of business, or any shopping location, ask you waiter or waitress, bartender, server, sales clerk, or cashier personal questions about their family or their interests.How much information are you able to obtain about this person you do not know?

Name, address, age, religion, political beliefs, place of birth, pets, hobbies, number of children, type of car they drive, or any other information you think you can obtain.

Write your findings in either a list or in paragraph form.
