You have been assigned to investigate whether or not an employee at a local hospital has been accessing patient records and selling information to online pharmacies. It is your first day of the investigation. Put together a list of data sources that must be examined during the investigation.

In 300 words

Instructions

You are to design an app for diversity awareness.

In order to analyze what to put in it, as well as to launch a marketing/sales plan you got a hold of a data set that indicates racial composition and diversity index for all counties in the US and their states. The dataset you need to work with it for this homework is attached (csv file).

1.  Obtain the descriptive statistics (quartiles) and the average diversity index for CA and for IL.
2. Also, obtain the descriptive statistics (quartiles) and mean of the Mixed Race population in NY and CA
3. Using a histogram, show the distribution of diversity index in IL and in CA (Show the histogram)
4. Based on your observations, what can you infer is different between the two states? Look at Cook County and other counties downstate. Does that help explain the different histograms? 
5. In which states are the top counties with the largest Hispanic population? and the counties with the largest White alone population? Where are the counties with the largest mixed population?. This question asks you to look at the country as a whole, not at a state by state level. Respond by looking at the top 10 counties and show the state with the most counties in that list.
6. Do CA and AK have a different diversity index? (i.e. does one have a significantly greater diversity index than the other?) Hint: look at the p-values
7. Do CA and IL have a different diversity index? Hint: same as above
8. Do IL and WY have a different diversity index? Hint: same as above.
9. Are these results intuitive? Explain them using histograms and/or boxplots

Your work must comply with the following:

• All questions answered in order. Please put the question number next to the answer
• Answer the questions sequentially.

Scenario:

You have been tasked with building a PC from scratch for a user named Joe.  Joe will be using this PC for high end gaming along with everyday tasks such as e-mail and web browsing.  Cost is not a constraint, but Joe would like the best bargain he can get.  Write a report detailing what you recommend for each component of the system and why.  Note that the details of the scenario are left deliberately vague.  Have some fun with this!  Design a top end system for the best price you can get.  Be creative!

In the below list, the first part of each item is the PC component, and it is followed by its specifications that need to be included in your report.  For instance, first in the list is the PC component “Operating System.”  It is followed by its specifications of which version of Windows you are choosing and either 64 or 32 bit.  

Make sure and address the following components and their specifications:

• Operating System
• What version? (Windows 10, 8, 7, etc.) 
• 64 or 32 bit
• System Board
• What form factor?
• What socket type for your processor?
• What front-side bus specs? Is it fast enough?
• What type of chipset?
• What type of RAM does it support?  How many slots?
• How many connections are there for drives?
• How many expansion slots are there?  Are there enough to support the needed cards?
• Video Card– performance, compatibility with system board, output ports
• Is the performance of your card sufficient?
• Is it compatible with your system board?  
• What type of output ports does it have?  Will these support the necessary devices?
• Case
• Is the size of your case sufficient to support your chosen board and number of drives?
• Power Supply
• Does it have the required wattage?
• Does it have enough connectors to support all devices?
• Does it fit in your case?
• Processor
• Is it compatible with the socket type?
• Is it compatible with the system board?
• Is it fast enough?
• 64 or 32 bit?
• What type of cooling system?
• RAM
• How many sticks?
• How fast?
• What type and size?
• Is it compatible with your system board?
• Peripherals
• What keyboard and mouse?
• Will you recommend a joystick?
• What speakers and/or headphones?
• Is a printer needed?
• Video
• What monitor type? (LCD, LED, Plasma, etc)
• How many monitors?
• What is the resolution and aspect ratio?
• What type of connectors are needed?
• Data Storage
• How many drives?
• How much storage space per drive is needed?
• How fast should the drives be?
• What type of drive? (HDD, SSD, SSHD, etc.)
• Internal and/or external?
• Input/Output Ports and Cables
• What type? (DVI, VGA, DisplayPort, etc)
• What speed?
• What length should they be?
• Network
• What type of NIC? (wired and/or wireless?)
• How fast?
• What type of addressing (static or dynamic)

Requirements and details:

-At least four pages long (it can be longer) double spaced using Arial 12 point font and 1 inch margins.  Note that the title of the document and any header will NOT be counted as part of the length.

-Provide links to all PC components you are recommending (this doesn’t count towards the length)

 From a development team of one to two people to an enterprise-level team with multiple divisions, the topic of mobile development will eventually come up. Write a four page research paper in which you:

• Compare & Contrast mobile applications vs websites (what makes mobile apps different from websites and necessary?).
• Research and discuss issues in developing a mobile strategy – use these issues about 3) to drive your research and the results you find.
• Discuss different system mobile functionalities.
• Explain the social aspect of mobile interfaces.
• Discuss two – three mobile application development myths.
• Argue the need for adaptive vs dedicated mobile websites.

Presentation for week 7 of my Comm120 class done on the Stanford prison project 

 Given the rich and diverse skills and mindset of an ethical hacker (technical, administrative, and physical measures), which characteristics do you believe to be the most important in this role? Please explain your choice. 

Critical thinking 1: 

Conduct research and write a paper on either mobile technologies or the Internet of Things (IoT). In your paper, address the following:

• Briefly define the technology      (collaborative technologies or IoT technologies), Also discuss how does it      works?
• Why are organizations applying      this technology? Identify and describe one real-world example.
• Explain why it is beneficial to      study IT today? Also discuss, does the technology reduce costs?
• How does the technology benefit      the organization’s internal and external users?
• What are some challenges or      potential problems of the technology to the organization?
• In your opinion, do the      benefits outweigh these concerns? Explain.
