Arrays are a collection of similar data types while classes are a blueprint for creating objects.

• Arrays store data in a contiguous memory location while classes define properties and methods for objects.

• Arrays can be accessed using an index while classes can be instantiated to create objects.

• Arrays are used for storing and manipulating data while classes are used for creating objects with specific behaviors.

• Example of ...read more

Arrays are a collection of similar data types while classes are a blueprint for creating objects.

• Arrays store data in a contiguous memory location while classes store data in separate memory locations.

• Arrays can be accessed using an index while classes can be accessed using object references.

• Arrays are used for storing and manipulating data while classes are used for creating objects with properties and methods.

Polymorphism is the ability of an object to take on many forms.

• Polymorphism allows objects of different classes to be treated as if they are of the same class.

• It is achieved through method overriding and method overloading.

• Example: A shape class can have different subclasses like circle, square, and triangle, each with their own implementation of the draw method.

• Polymorphism makes code more flexible and reusable.

Abstraction is the process of hiding complex implementation details and showing only the necessary information to the user.

• Abstraction is a fundamental concept in object-oriented programming.

• It helps in reducing complexity and increasing efficiency.

• Abstraction can be achieved through abstract classes and interfaces.

• For example, a car dashboard is an abstraction of the car's internal workings.

• Another example is a TV rem...read more

Class is a blueprint for objects while interface defines a contract for classes to implement.

• A class can have attributes and methods while an interface only has method signatures.

• A class can be instantiated while an interface cannot.

• A class can only inherit from one class while it can implement multiple interfaces.

• Example: Class - Car, Interface - Drivable

• Car can have attributes like color, model, etc. while Drivable o

OS manages hardware and software resources to provide a user-friendly interface for running applications.

• OS communicates with hardware components to manage resources like memory, CPU, and storage.

• It provides a user interface for running applications and manages input/output operations.

• Examples of OS include Windows, macOS, and Linux.

• OS also manages security and permissions for users and applications.
