displays a GUI, allocates the computer's resources, and retrieves files

The operating system can be defined as the software installed in the system that provides the information and services to the users by controlling the hardware, software resources, and regulates the computer programs. It runs the applications and programs in the system, displays the graphic user interface for the services, stores, manipulates, and retrieves files.

What are the multiple choice answers?
Answer:
B. Graphs
Explanation:
Graphs are used to put certain things into categories. In this case Jamie has to enter different categories such as names, grades and the scored of the students. C and D don't make sense for this problem since they aren't actually what he is looking for. A is plausible but he needs it into a worksheet and labels aren't worksheets they are just labels. So B would be your answer. Also I took the quiz this is the correct answer.
Answer:
import java.util.Scanner;
public class ss11{
public static void main (String[]args) {
Scanner keyboard = new Scanner (System.in)
String a1, a2, a3, a4, a5;
int i1, i2, i3, i4, i5;
System.out.println("Enter a four bit binary number:");
a1= keyboard.next();
a2= a1.substring(0,1);
a3= a1.substring(1,2);
a4= a1.substring(2,3);
a5= a1.substring(3,4);
i1 = Integer.parseInt(a2);
i2 = Integer.parseInt(a3);
i3 = Integer.parseInt(a4);
i4 = Integer.parseInt(a5);
i1= i1 * 8;
i2= i1 * 4;
i3= i1 * 2;
i4= i1 * 1;
i5= i1+i2+i3+i4;
System.out.println("The converted decimal number is: +i5);
}
}
