Answer:
D. Power cords to the motherboard are not connected.
Explanation:
The correct option is the power cord that supplies electricity to the motherboard is not connected. The idea that there's no light or sound indicates the system isn't on or booting. The only option there that indicates why the computer may not boot.
Other options available albeit creates a problem for the computer, will still turn on the computer. But if the motherboard doesnt get power, the booting process doesn't start.
Answer:
Project life cycle is the time taken to complete a project, from start to finish.
The three project life cycles model include the following:
- Predictive
- Iterative and Incremental
- Adaptive
Explanation:
Predictive project life cycles model: In this stage, the three major constraints of the project which are the scope, time and cost are analyzed ahead of time and this analysis is well detailed and the detailed scope of the project is done right from the start of the project.
Iterative and Incremental life cycles model: In this iterative and incremental model, the project is again split into stages that can be sequential or overlapping and at the first iteration of the project, the scope is determined ahead of time.
Adaptive life cycles model: Also in this stage, the project is split up into phases but because these phases are more rapid and ever changing unlike the other models, the processes within the scope can work in parallel.
Similarities
- They make use of high level planning.
- They are sequential and overlapping.
- They make use of high level scope.
Differences
- The predictive life cycle model makes use of a detailed scope at the beginning of a project while the other models make use of detailed scope only for each phase.
- In predictive life cycle model, the product is well understood, in other models, the projects are complex and not easily understood.
- There is periodic customer involvement in predictive and interative life cycle model while the customer involvement in the adaptive model, the customer model is continuous.
Answer:
See explaination
Explanation:
//class extends Exception
class ParameterNotAllowedException extends Exception {
//Instance variable
private int input;
//Argumented constructor
public ParameterNotAllowedException(String message, int input) {
super(message);
this.input = input;
}
public int getInput() {
return input;
}
public void setInput(int input) {
this.input = input;
}
atOverride // Replace the "at" with at symbol ie shift 2
public String getMessage() {
//Returns the message
return input+" is invalid. "+super.getMessage();
}
}
class Main {
public static void main(String[] args) throws ParameterNotAllowedException {
int n = -1;
//Throw negative not allowed exception
if(n<0){
throw new ParameterNotAllowedException("negative number",n);
}
}
