UNIT 1 ACTIVITY Troubleshooting

Part A

When your friend DaJuan turns on his computer, he hears four beeps. The computer

won't fully boot. DaJuan has a Dell computer with a quad core processor and has

recently upgraded his RAM.

Apply the troubleshooting methodology to help DaJuan understand and resolve his

problem. The steps of the methodology are listed for you. You can write directly on

the write suggestions for DaJuan at each step.

1. Identify the Problem (beeps are key here)

2. Internet Research

3. Establish a Theory of Probable Cause

4. Test the Theory

5. Establish a Plan of Action

6. Implement the Solution or Escalate

7. Verify Full System Functionality

8. Document Findings

A.) generate scaffolding to create database for your application. develop all the entities identified in assignment #2. add any additional that may be identified later. b.) add data validation rules to the models that are appropriate for your application and data. c.) create links for each scaffold in the header section. part 2: application updates [30 points] a.) add two additional views to the "home" controller you created in assignment #1. b.) the two views should be named as “privacy" and "". c.) link the two newly created views in the footer section. hint: you would need to modify the “home" controller definition and create “privacy.html.erb" and “.html.erb" files in appropriate locations.

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;

Match the items with their respective descriptions.
