What are the differences between 802.11b, 802.11a, 802.11g, and 802.11n wireless LANs? Do you think standards are beneficial in wireless networking or do you think they limit new technologies? Explain your answer.

Discussion 1:  

This week, you covered Azure identity management, policy, and compliance. Think about how seriously Microsoft takes these matters, including meeting the federal government FedRAMP requirements.  

As a user of cloud services, why would Azure FedRAMP certification matter to you? Explain the differences between high and moderate FedRAMP ratings. 

You have been hired to perform digital investigations and forensics analysis for a company . You find that no policies, processes, or procedures are correctly in place. Do an internet search to find information, and then create a policy and processes document to provide the structure necessary for your Lab environment. Be sure to cite your online sources.

TWO PAGES WITH SO MANY REFERENCES FROM ONLINE AND ELSEWHERE BUT NO PLAGIARISM.

1 . It is perfectly fine to slightly modify the code so that it runs on Python 3.x instead of 2.x. Please be sure to include a short note documenting the change you made to get it to run (it should be very minor). Do not use Jupyter notebooks, R or some other language. You must fill in the .py file to receive a grade.
3. For EVERY unique map reduce job, you have to clear out the global data structures! Otherwise, you’re persisting information from one MR job to the other, and you will get wrong results. The following may help to clarify: (a) a map reduce JOB is run over a set of documents (the ‘corpus’) since you’re doing word count over a corpus, (b) when computing the execution times of map and reduce, make sure to take this into account. Specifically, you will have to ADD (not average) the execution times for a mapper over the corpus (e.g., if the mapper takes 3 seconds to process doc_1, 2 seconds for doc_2 and 4 seconds for doc_3, the total time taken by the mapper is 9 seconds). You are, of course, generating corpora ten times for each document length (say 10). This will give you ten mapper and ten reducer times for that length. These ten numbers will (respectively) each be averaged into one, and these averaged numbers will be your ‘data point’ for that length, along with error bars. You can use any tool you want for visualization (Excel works well enough, but you could use matplotlib, or other external tools. The plots will be attached with your submission).  
4. In your submission, try to be as organized as possible, but you should absolutely include all supporting data that you can, including plots and raw timing data that you used for the plots. Like real life, the HW doesn’t have a single right or wrong answer. We are more interested in seeing the effort you made and good reasoning for decisions or assumptions you found yourself making in the context of the assignment.

The World Meteorological Organization (WMO) has hired you to write a data structure that stores record temperatures across the globe. Incoming temperature reports have very precise geo-location data (latitude and longitude coordinates). The WMO would like for you to store data in a “grid”, treating any points that round to the same latitude and longitude within one decimal as the same. Note that we are using negative numbers for southern latitudes and western longitudes, so the above coordinates correspond to (36.4° N, 105.0° W). Write a data structure TempMap that keeps track of the hottest and coldest temperatures for each reported coordinate. There is a lot of data coming in, so you need to read and write this information quickly – you should be able to update the record at a (lat, long) pair in O(1). Do not use the built-in set or dictionary types in this assignment. class TempMap Write a class TempMap that keeps track of the maximum and minimum temperature for each reported set of coordinates. Magic Methods init O(1) in O(1) Returns True (False) if the rounded version of a specified coordinate is (is not) in this collection get O(1) Returns a tuple containing the (min, max) temperatures at these coordinates Raise a KeyError if the specified coordinate are not in this collection the input coordinates may or may not be rounded Non-Magic Methods add_report(pos, temp) O(1) pos – an (unrounded) tuple of coordinates temp – the current temperature at those coordinates Updates the maximum or minimum recorded temperature for pos if appropriate remove_pos(pos) O(1) removes the record for the given position from this collection raises a KeyError if pos is not in this collection Special Behavior Memory constraint – you should limit your memory usage to be between 1/2 and 2x the amount necessary to store the number of unique coordinates – that is, you should periodically increase and decrease the amount of memory used as items are added and removed. The starter code includes a function generate_report that returns a randomly generated tuple of (lat, long, temperature). Feel free to use it to help with testing

1. Which is your “favorite” attack? Why? Which is the most dangerous? Which do you think is the hardest to protect against?
2. Have you ever used e-mail or instant messenger to share information that was sensitive in nature? Have you ever gotten spam? Have you ever responded to spam? Have you tried to remove your name from the list? Did it work? Do you have any idea how your e-mail address wound up on the spam list in the first place?

Working on Finishing it up. Information provided in attachments 

The project must be a Word document that is 500-700 words, double spaced paper, written in APA format, showing sources and a bibliography on CITIZEN RIGHTS VS SECURITY. It will run through SafeAssign and Any assignments that have a 25% similarity rate or higher, it will get a zero. It will also require a presentation.
