Natural systems are systems that came into being by natural processes. Like the rain cycle.
Technological systems are those to whom people intervened or designed. Like diverting water for a rider for land irrigation.
Answer: Memory hierarchy is the hierarchy that is created on the basis of the response time of different memories. The performance obtained by the memory helps in creating a computer storage space in distinguished form. The factors considered for the creating of the hierarchy structure are usually response time, storage capacity, complexity etc.
Usage of different kind of memories take place due to different kind of requirements from the system which cannot be fulfilled using one memory device.The requirement is based on saving time, decreasing complexity , improving performance etc.Example of requirements can be like some functions and files do not require much space , some might require quick accessing,etc.
Thus hierarchy of any particular system is in the form of fast to slow order from registers,cache memory, Random access memory(RAM) and secondary memory.
Answer:
b. data type of arguments
Explanation:
One of the ways to overload a method is using different type of arguments. Let's say we have a method that finds and returns two integer values
public int sumValues(int num1, int num2){
return num1 + num2;
}
We can overload this method by passing double values as arguments
public double sumValues(double num1, double num2){
return num1 + num2;
}
The answer is (C) IT careers are found in a wide variety of industries.
Nowadays, all types of industries in various different parts of the world will have an IT (information technology) department because it is needed, since most businesses operate using some form of IT equipment, which, most commonly found is a computer. It is a particularly lucrative field because of the wide array of job availability.
Answer:
- import java.util.Scanner;
- public class MealPriceCalculation{
-
- public static void main(String[] args) {
-
- Scanner input = new Scanner(System.in);
- System.out.print("Enter meal price: ");
- double meal = input.nextDouble();
- System.out.print("Enter tip: ");
- double tip = input.nextDouble();
-
- calculatePrice(meal,tip);
- calculatePrice(meal,(int)tip);
-
- }
-
- public static void calculatePrice(double meal, double tip){
- System.out.println("Total meal price: $" + (meal + tip) );
- }
-
- public static void calculatePrice(double meal, int tip){
- System.out.println("Total meal price $" + (meal+tip));
- }
- }
Explanation:
The solution code is written in Java.
Overload methods are the methods that share the same name but with different method signature. In this question, we create two overload methods calculatePrice (Line 17-23). One version will accept parameter meal and tip in double type and another will accept parameter meal in double but tip in integer. Both of this method are doing the same job which is just printing the total of meal.
In the main program, create a Scanner object and use it to prompt user to input meal price and tip (Line 6-10). Next call the calculatePrice method for twice. In the first time, pass meal and tip as double type data to calculatePrice method (Line 12). In the second time, pass meal in double but tip in integer to the method. Only the method with parameter list that match the argument data type will be implemented and output the total meal price.
