1.   Do you believe that all data should be encrypted? Many computing professionals think this is a good idea. But a small number of computing experts feel that no data should be encrypted—that all data and software should be openly available to anyone who wants it. Explain your answer (whether you believe all data should or should not be encrypted). (2-3 paragraphs)

2.  In this module, you learned that random numbers (or, at least, pseudorandom numbers) are essential in cryptography, but it is extremely difficult even for powerful hardware and software to generate them. Go online and conduct research on random number generators. What are the different uses of these tools besides cryptography? How do they work? Explain your answer using your own words in 2-3 paragraphs. 

NO PLAGIARISM 

Do you feel that countries and companies need explicit strategies for technology development, given the tremendous amount of largely spontaneous creativity that occurs today, often in areas where new technologies are not expected to exert a great influence.  Why or why not?

Propose and defend a topic for your final project.  Write  500 words or more explaining why this topic is important for your peers to understand. Be focused and specific. Look into the general topic provided in the list in this folder to find something new and interesting to write about. You should do a deep dive into a topic. Do not do a survey. Use the Research Databases available from the Danforth Library not Google. 

You MUST make a statement saying exactly what your topic is. 

Use at least five sources. Include at least 3 quotes from your sources enclosed in quotation marks and cited in-line by reference to your reference list.  Example: “words you copied” (citation) These quotes should be one full sentence not altered or paraphrased. Cite your sources.

Copying without attribution or the use of spinbot or other word substitution software will result in a grade of 0. 

Write in essay format not in bulleted, numbered or other list format. 

Do not use attachments as a submission. 

Respond helpfully to two classmates’ posting in a paragraph of at least five sentences by asking questions, reflecting on your own experience, challenging assumptions, pointing out something new you learned, offering suggestions. Write to help them focus and say something that you think would help them say something that would be valuable.    You should make your initial post by Thursday evening so your classmates have an opportunity to respond before Sunday.at midnight when all three posts are due. 

It is important that you use your own words, that you cite your sources, that you comply with the instructions regarding length of your post and that you reply to two classmates in a substantive way (not ‘nice post’ or the like).  Your goal is to help your colleagues write better. Do not use spinbot or other word replacement software. It usually results in nonsense and is not a good way to learn anything. Please do not use attachments unless requested

Chapter 1 Paper: Review the Key Lessons from Chapter 1 – Explain the five key lessons and note the importance of each key lesson from chapter 1.  Also, note why is it important to understand these basic concepts.  (Information Technology and Organizational Learning Textbook) 

The above submission should be one page in length and adhere to APA formatting standards.

Prepare a 3 page report and a short powerpoint presentation on the topic mentioned above. More details given below.

Imagine that a company wants to know all the important things about the design/structure/architecture (* important – not just user interface features) and the applications in  solaris operating system, and that company has assigned you the task of writing a report and presenting your findings to the managers and technical staff of that company.  Concentrate on the “big picture” first, that is, the most important things about whatever system(s) or approach you are studying. Don’t let your audience/readers get bogged down  in unimportant details. Only if fine details serve to help to understand the big picture, would you use those fine details as examples to illustrate how the important things work.  

How the topic study will be evaluated:  

The topic study will be evaluated according to:  

(a) The quality, clarity, and completeness of the report and presentation.   

(b) Whether the most interesting and most important facts about the topic were emphasized and clearly presented in the report and presentation.

The format for the references in the topic study, should be similar to the format of the references in the paper i have attached.

 Note: This one IP is worth 200 points. Parts 1 and 2 together are worth 100 points. Part 3, which is “summative” is worth 100 points. Part 1: In a two-phase, total-order multicast system, messages are sent in the following sequence from node S to G1 and G2. G1 and G2 are the members of the group. 1. S sends m1 to G1 2. S sends m1 to G2 3. S sends m2 to G2 4. S sends m2 to G1 Use the basic implementation of the Lamport clock. The clock s at each node start at: S: 4, G1: 6, G2: 1 Show the exchange of messages and their acknowledgments in a clock diagram using the basic implementation of Lamport’s clock. In which order and at what times are m1 and m2 delivered? Part 2. Draw a state diagram of Maekawa’s voting algorithm on the slide “Maekawa’s algorithm” in the “Distributed mutual exclusion” slide set. Note that the state diagram is from the point of view of any one of the nodes, called “this” node below. The state diagram cannot show the states of other nodes. i) Start with the basic case where “this” node wants the lock, gets it, and then releases it, and no other node wants the lock at the same time. In this case, “this” node goes through all the states in this order: Released and not voted Wanted and not voted Wanted and voted Held and voted Released and voted (Back to) Released and not voted Events are: acquire for when “this” node wants the lock release for when “this” node gives up the lock. 8/7/20 3:01 PM 15 request_received, reply_received, and release_received when a message from any node arrives at “this” node. The state diagram is similar the one of Ricart and Agrawala’s state machine (in the Distributed Mutual Exclusion PowerPoint deck) but has more states. *** If you do part i) more or less correctly, you will earn most of the points. *** ii) The complete solution includes the situations where “this” node votes on requests from other nodes. The states are the same as above, but there are additional transitions and actions. Use the “Maekawa scenario” slide in the Distributed Mutual Exclusion slide set, or Fig. D-10 in the Study Guide. Warning: There is an incorrect solution for this problem on the Web. It has extra, incorrect states. Part 3 (100 points): Summarize the course in your own words in an essay of 5-6 pages or so. Feel free to reuse any relevant DB posts as well as Unit 3 IP, but please correct any errors found. Edit it all into one paper that reads nicely from top to bottom and is styled according to APA. Include at a minimum: • How threads and safe objects interact. This can be in general or based on Ada or Java. • Entity-life modeling: the idea of finding event-sequence models of the domain and map them onto thread architectures in the software. Deadlock prevention. • The use of logical clocks for communication and/or for distributed mutual exclusion.

You will review both quantitative and qualitative research.  The topic is up to you as long as you choose a peer-reviewed, academic research piece.  I suggest choosing a topic that is at least in the same family as your expected dissertation topic so that you can start viewing what is out there.  There are no hard word counts or page requirements as long as you cover the basic guidelines.  You must submit original work, however,  and a paper that returns as a large percentage of copy/paste to other sources will not be accepted.  (Safe Assign will be used to track/monitor your submission for plagiarism. Submissions with a Safe Assign match of more than 25% will not be accepted.) 

Please use APA formatting and include the following information:

• Introduction/Background:  Provide context for the research article.  What led the author(s) to write the piece? What key concepts were explored? Were there weaknesses in prior research that led the author to the current hypothesis or research question?
• Methodology:  Describe how the data was gathered and analyzed.  What research questions or hypotheses were the researcher trying to explore? What statistical analysis was used?
• Study Findings and Results:  What were the major findings from the study? Were there any limitations?
• Conclusions:  Evaluate the article in terms of significance, research methods, readability and the implications of the results.  Does the piece lead into further study? Are there different methods you would have chosen based on what you read? What are the strengths and weaknesses of the article in terms of statistical analysis and application? (This is where a large part of the rubric is covered.)
