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).

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

• Please read these two articles:
• Using forensics against a fitbit device to solve a murder:  https://www.cbsnews.com/news/the-fitbit-alibi-21st-century-technology-used-to-help-solve-wisconsin-moms-murder/
• How Amazon Echo could be forensically analyzed! https://www.theverge.com/2017/1/6/14189384/amazon-echo-murder-evidence-surveillance-data
• Then go around in your residence / dwelling (home, apartment, condo, etc) and be creative.
•  Identify at least five appliances or devices that you THINK could be forensically analyzed and then identify how this might be useful in an investigation. Note – do not count your computer or mobile device. Those are obvious!
• I expect at least one paragraph answer for each device.
