The control of the serialization of memory management is difficult in a “Virtual Memory” and especially when “Virtual Machines” are included. Discuss how an operating system manages “computer memory in both single and multiple OS instances”. Add discussions about how some of the problems have been addressing including respective advantages and disadvantages.

 

Sometimes you need to see how an application works and behaves on a booted suspect’s computer. For this project, write a short guideline of two to three pages on how to use VirtualBox to start and run applications from a suspect’s disk image. Your research should start with the VirtualBox user guide at www.virtualbox.org. For more information, search for terms such as “VirtualBox convert RAW image to VDI” or “convert raw to vmdk.”

2. Create 2 Python programs based on week 5 Assignment flowcharts and requirements. You must use loops, do not use function calls.

 

Here is a SAMPLE run for a simple calculator to add to numbers (this is for reference only)

Simple Calculator

What is your name –> Supa

Enter first number –> 7

Enter second number –> 5

Supa, The total of 7.0 + 5.0 = 12.0

Do you want another calculation ? (y/n) y

What is your name –> Lupa

Enter first number –> 21

Enter second number –> 11

Lupa, The total of 21.0 + 11.0 = 32.0

Do you want another calculation ? (y/n) n

Thanks for using my calculator

Read the attached Ethics-V.pdf Download Ethics-V.pdfwhich continues the discussion on the professional codes of software engineering ethics.

Then proceed to answer the questions inside the reading:

 Question 8:1: Read over Appendix A and B. Identify two code items from
Appendix  A  and  two  from  Appendix  B  about  which  you  have  either:  a  question
concerning  its  meaning,  a  comment  about  its  importance,  or  a  concern  about  its
ability to be well implemented.  Pose those questions/comments/concerns below.

Question  8:2:  How  might  the  qualities  of  a  ‘superprofessional’  engineer  with
practical  wisdom,  as  described  in  this  section,  assist  such  a  person  in  applying
these codes successfully?  Be specific.  

 Question   C:1: What forms of harm did members of the public suffer as a result of
Google StreetView images?  What forms of harm could they have suffered as a
result of Google’s data-collection efforts?

Question   C:2: What institutional and professional choices might have been
responsible for Google StreetView’s violations of public privacy?

Question  C:3:  What ethical strategies from your earlier reading in this unit could
Google engineers and managers have used to produce a more optimal balance of
functionality and ethical design?  Could one or more Google ‘superprofessionals’
have prevented the privacy breaches, and if so, how?

Question  C:4:  What can Google do now  to prevent similar privacy issues with its
products in the future?  

 

Because for many ethics questions there is no absolutely right or wrong answers as such, your responses will be graded based on completeness and thoughtfulness as opposed to rote or perfunctory ones. There are three grade levels for this assignment based on your responses to all the questions: 20 (no reasoning in responses), 35 (minimal to little reasoning), and 50 (sufficient reasoning and consideration).

Write your answers in a Word file using Times New Roman font (no smaller than 10 pt but no bigger than 12 pt), single spacing, 1″ margins on all sides.
