In 80 words or more explain what does the Chief Data Officer have to do with EDMS and data? 

Paste the code into MIPS 

Next, please comment each line of code in the .text section. Please do this FIRST! It will make tracing through the code much easier. 

Once you understand what the code is doing, you’ll notice there is a ‘print_a’ function that is not reachable through the execution path of the code as it’s written. Your job is to devise an input that overflows the call stack and overwrites the $ra register causing the program to execute the ‘print_a’ function. Please provide the successful input that triggers the overflow, a screenshot of the successful execution of your attack that prints the A+ message, and a detailed description of how you figured out how to exploit the buffer overflow and how you devised the proper input. 

Code used for the assignment above

.data

    str: .asciiz “You’ve earned an A+!”

    buffer: .space 28

.text

    li $v0,8

    la $a0, buffer

    li $a1, 28

   move $t0,$a0

    syscall

    move $a0, $t0

    jal print

   li $v0, 10

   syscall

    print:

     addi $sp, $sp, -20

     sw $ra, 16($sp)

     sw $a0, 12($sp)

     addi $t4, $sp, 0

     la $t1, ($a0)

     load_str:

   lbu $t2, ($t1)

   slti $t3, $t2, 1

   beq $t2, 48, null

   resume:

         sb $t2, 0($t4)

         addi $t4, $t4, 1

         addi $t1, $t1, 1

         bne $t3, 1, load_str

        li $v0, 4

        syscall

        lw $ra 16($sp)

        lw $a0 12($sp)

        jr $ra

        null:

     addi $t2, $t2, -48

     j resume

print_a:

    li $v0, 4

    la $a0, str

    syscall

The major team research project will be turned in during residency weekend.  Each student will be assigned to a group (Executive Team) to complete the project. The research project will focus on research related to a cloud computing topic of your team’s choice.  Pre-work on the project including the proposed Title and Outline should be emailed to the professor early for review and acceptance on Saturday afternoon.  The team should then begin to work on the project Saturday afternoon of the residency to be sure it can be completed during the Residency weekend. 

Requirements for the research paper include… 

• Must be written in APA format and should be 20-25 pages long. 

• Contain at least 3-5 works cited (references)

• At least 2 of the works cited should be peer-reviewed articles ( not more than 5 years old)

• No Wikipedia citations

 Go online and research some tools that would be valuable in collecting both live memory images and images of various forms off media. Put together a shopping list for your manager that includes tools needed  to be purchased. Include a price if applicable. 

Many organizations lack a clear and concise security policy. Without a policy there is often an inconsistency in security focus by employees and management and increased opportunities for experiencing security incidents.

Respond to the following in a minimum of 175 words:

• Search the internet for two companies’ policies.
• Analyze the policies to determine commonalities.
• What would be your top three concepts that should be included in an organizational security policy mission statement? Explain your reasoning for your listed three concepts.

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?

how Big Data analytics can be used with Smart Cities. This is exciting and can provide many benefits to individuals as well as organizations. For this week’s research assignment, you are to search the Internet for other uses of Big Data in RADICAL platforms. Please pick an organization or two and discuss the usage of big data in RADICAL platforms including how big data analytics is used in those situations as well as with Smart Cities. Be sure to use the UC Library for scholarly research. Google Scholar is the 2nd best option to use for research.

Your paper should meet these requirements:

• Be approximately four to six pages in length, not including the required cover page and reference page.
• Follow APA 7 guidelines. Your paper should include an introduction, a body with fully developed content, and a conclusion.
• Support your answers with the readings from the course and at least two scholarly journal articles to support your positions, claims, and observations, in addition to your textbook. The UC Library is a great place to find resources.
• Be clearly and well-written, concise, and logical, using excellent grammar and style techniques. You are being graded in part on the quality of your writing.
