Operating System Questions

1. What is Method Overloading?
Answer: Method overloading is a feature in Java (and other object-oriented languages) that allows a class to have more than one method with the same name, but different parameters. The parameters can differ by the number of parameters or their types. Method overloading is a compile-time polymorphism.

Example:


class MathOperations {
// Overloaded method: no parameters
public int add() {
return 0;
}

// Overloaded method: one parameter
public int add(int a) {
return a;
}

// Overloaded method: two parameters
public int add(int a, int b) {
return a + b;
}

// Overloaded method: different parameter types
public double add(double a, double b) {
return a + b;
}
}


2. What is the meaning of Method Overriding?
Answer: Method overriding is a feature in object-oriented programming where a subclass provides a specific implementation of a method that is already defined in its superclass. The method in the subclass must have the same name, return type, and parameters as the method in the superclass. Method overriding is used for runtime polymorphism.

Example:

class Animal {
public void sound() {
System.out.println("Animal makes a sound");
}
}

class Dog extends Animal {
@Override
public void sound() {
System.out.println("Dog barks");
}
}


3. How can data abstraction be accomplished?
Answer: Data abstraction is accomplished in object-oriented programming through the use of abstract classes and interfaces. Abstraction is the concept of hiding the implementation details and showing only the functionality to the user. It helps in reducing complexity and allows the programmer to focus on interactions at a higher level.

Example using Abstract Class:


abstract class Shape {
abstract void draw(); // Abstract method
}

class Circle extends Shape {
void draw() {
System.out.println("Drawing Circle");
}
}

class Square extends Shape {
void draw() {
System.out.println("Drawing Square");
}
}


Example using Interface:


interface Drawable {
void draw(); // Abstract method
}

class Circle implements Drawable {
public void draw() {
System.out.println("Drawing Circle");
}
}

class Square implements Drawable {
public void draw() {
System.out.println("Drawing Square");
}
}


4. What is Thrashing?
Answer: Thrashing occurs in a computer system when there is excessive paging, which leads to a significant slowdown in performance. It happens when the system spends more time swapping pages in and out of memory than executing actual processes. This can be caused by having too many processes competing for too few memory resources, leading to a high rate of page faults.

Example: Consider a situation where multiple programs are running simultaneously, and each program requires more memory than is available. The operating system will continuously swap data to and from the disk, causing a severe drop in system performance.

5. What is Banker's Algorithm?
Answer: The Banker's Algorithm is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra. It is used in operating systems to allocate resources to processes in such a way that the system remains in a safe state, avoiding deadlock. The algorithm checks whether granting a particular request will leave the system in a safe state, where a safe state means that there is at least one sequence of process execution that does not result in a deadlock.

Example: The algorithm considers the maximum possible resources that each process may request and ensures that the total resources allocated do not exceed the available resources at any time.
