Answer:
Sound card
Explanation:
In computer or laptop music or sound files are stored in digital form. Sound card is the the device that is used to convert the digital form of music into analog to produce the signal that is compatible with speaker or microphone.
If the speakers are not working on the laptop, means there is no sound produced on speakers. It means that sound card is not working properly.

Answer:
The difference is that a floppy relies on a floppy disk reader to spin its disk, where as a hard drive is a fully enclosed container that has it's reader enclosed as well. A floppy disk is a single plastic film disk, where as a hard disk can have multiple metal disks.
Explanation:
Answer:
The output is "A"
Explanation:
public class Solution {
public static void main(String args[]) {
mystery(7);
}
public static void mystery(int a) { System.out.println("A"); }
public static void mystery(double a) { System.out.println("B"); }
public static void mystery(int a, double b) { System.out.println("C"); }
public static void mystery(double a, int b) { System.out.println("D"); }
}
In the code above; mystery is defined in four different ways called method overloading. Method overloading is when same method is defined with different parameters.
In the first case; mystery will be called if the argument is int.
In the second case; mystery will be called if the argument is double.
In the third case; mystery will be called if the arguments are int and double.
In the fourth case; mystery will be called if the arguments are double and int.
When mystery(7) is called; the mystery method requiring only int will be called and the output is "A".
The equations that uses addition, subtraction,
multiplication and division operators and other values in a spread sheet is
known as formulas. They are a way of having to provide symbols in means of
expressing information regarding a mathematical formula that are being solved
or showing its solution along with it.
