 Lists and dictionaries are two of the most popular abstract data types in Python. Like most data types, each has its own specific uses in code. This week we will concentrate on lists.   

• Describe what a list is in your own words.  
• Provide reasons as to when it makes sense to use it in your code.   
• Give an example of data that you feel is a good candidate for being stored in a list.
• Be sure to post a substantive response to one of your classmates’ posts and cite any resources used.

 . Evaluation MatrixCreate an Evaluation Matrix Chart in MS Excel comparing 3 technology careers for each criterion. What should be in the matrix:

• Three technology careers from Chapter 8. (i.e. system analysis, software engineer, help desk technician) to evaluate.
• Three criteria (all students must use these criteria).  
  • Salary – Look up the criteria for each of your careers/professions on the Bureau of Labor and Statistics Occupational Outlook Handbook at https://www.bls.gov/ooh/ and O*Net  https://www.onetonline.org/.  You may use other sources of information. 
  • Job Responsibilities Look up the criteria for each of your careers/professions on the Bureau of Labor and Statistics Occupational Outlook Handbook at https://www.bls.gov/ooh/ and O*Net  https://www.onetonline.org/.  You may use other sources of information.  
  • Career Outlook (what percentage of jobs will be available in the future) – Look up the criteria for each of your careers/professions on the Bureau of Labor and Statistics Occupational Outlook Handbook at https://www.bls.gov/ooh/ and O*Net  https://www.onetonline.org/.  You may use other sources of information. 
• Formulas in each cell – Use the videos in the Video Resource folder to learn how to create a excel worksheet, formulas, and chart in addition to Evaluation Matrix Example Criteria file in the section below.

Submitting the Assignment:Create 2 Excel worksheets.   

1. The first is your Excel matrix chart with formulas to calculate weighted scores and totals using a mixed cell reference. You will see which career scored best with the raw scores and which career scored best with the weighted scores. Divide 100 points among the criteria with the highest number of points going to the criteria most important to you.
2. The second is a chart of your results from the matrix.  The chart may be the style of your choice. It must give good information about the data in your worksheet with your matrix. Name each worksheet in the workbook appropriately. Submit your file with both worksheets into the Blackboard assignment.

An example of the matrix is in this section labeled Evaluation Matrix Tutorial as an attachment.  Watch videos in the video reference folder for guidance below.  Additional Resources available under GCFLearnFree.org section.Do not forget to record your sources/references in APA format.  Your graded on having all of the required information:

• Three technology careers 
• Three criteria   
  • Salary – Look up the criteria for each of your careers/professions on the Bureau of Labor and Statistics Occupational Outlook Handbook at https://www.bls.gov/ooh/ and O*Net  https://www.onetonline.org/.  You may use other sources of information. 
  • Job Responsibilities Look up the criteria for each of your careers/professions on the Bureau of Labor and Statistics Occupational Outlook Handbook at https://www.bls.gov/ooh/ and O*Net  https://www.onetonline.org/.  You may use other sources of information.

• Formulas in each cell 

Load the data file Crowdfunding_data_1000_projects.xlsx Download Crowdfunding_data_1000_projects.xlsxin a Pandas data-frame. Perform 70:30 split with 70% of records (rows) as train and rest 30 % of records as test using following three techniques:

1. Use Pandas functions head() and tail(), and create two data-frames with top 70 % records in the first data-frame, and remaining 30% records in the second data-frame (2 points).

2.  Use Pandas functions sample() and drop(), and create two data-frames with random 70% of records in the first data-frame and remaining 30% of records in the second data-frame (4 points). 

3. Use Scikit-learn package and create two data-frames with random 70% of records in the train data-frame and remaining 30% of records in test data-frame (4 points).

Upload one Jupyter Notebook file with code in the submission. 

Homework Content

For each of the following examples, determine whether this is an embedded system, explaining why or why not. 

Question 1 Are programs that understand physics and/or hardware embedded? For example, one that uses finite-element methods to predict fluid flow over airplane wings?

 
Question 2 Is the internal microprocessor controlling a disk drive an example of an embedded system? 

Question 3  Is an I/O drivers control hardware, so does the presence of an I/O driver imply that the computer executing the driver is embedded?

 
Question 4 Is a PDA (Personal Digital Assistant) an embedded system? 

Question 5 Is the microprocessor controlling a cell phone an embedded system? 

Question 6 Is the computer controlling a pacemaker in a person’s chest an embedded computer? 

Question 7 List and briefly define the possible states that define an instruction execution. 

Question 8 List and briefly define two approaches to dealing with multiple interrupts.

 
Question 9

Consider two microprocessors having 8- and 16-bit-wide external data buses, respectively. The two processors are identical otherwise and their bus cycles take just as long. 

(a) Suppose all instructions and operands are two bytes long. By what factor do the maximum data transfer rates differ? 

(b) Repeat assuming that half of the operands and instructions are one byte long.
