Part 1. Abstraction. 1. Create a table that shows the abstraction of a vending machine (such as a beverage or snack machine) from the perspective of the customer stakeholder. Have at least 4 columns and 2 rows in your table. You must include and identify each of the four basic data types in your answer. (Refer to think.co.vt.edu if needed.) Vending Machine Stakeholder: Customer 2. Sketch three versions of a vending machine in the space below, with each version demonstrating either high medium, or low levels of abstraction High Medium low Part 2: Problem-solving and Algorithms 3. Is this an example of a good algorithm? Why or why not? If not, how could it be improved (rewrite it? How to Buy a Snack from the Vending Machine Select the snack you want to buy Make sure you have the necessary amount of money, Enjoy your snack Answer the following questions based on the General Problem Solving Process and the scenario below: Assume that in December, UTEP student U. Miner took a look at the Spring 2021 tuition bill total and panicked, realizing the money s/he had worked hard to earn and set aside would not be enough to cover costs for all the courses needed. U. quickly reacted by dropping one class to reduce the bill to an affordable level, even though it would delay graduation Later, as U met with an advisor and saw the impact, W. had second thoughts on having taken that action 4. What step in the Problem Solving Process did U. probably fail to include? (Circle the letter of the closest answer) a. Reflection on how this financial situation developed over the months b. Quick implementation of steps to reduce the tuition bill for Spring so that current funds would be enough c. Identification of the need to have enough money to pay for Spring semester courses d. Generation of alternative ways to solve the problem, examining pros and cons for each Evaluation of whether or not dropping one course would lower the tuition bill enough 5. Explain the reason for your answer in 14 above, and how student U could have handled the problem differently. 6, Number (1:2, 3) each of the following developments in computer design in the correct order in time. Briefly explain how each works Vacuum tube Electro-mechanical Transistor
