MVC is a software design pattern that separates an application into three interconnected components: Model, View, and Controller.

• Model represents the data and business logic

• View displays the data to the user

• Controller handles user input and updates the model and view accordingly

• MVC promotes separation of concerns and modularity

• Examples: Ruby on Rails, ASP.NET MVC, AngularJS

Minification & Bundling are introduced in MVC to improve web application performance.

• Minification reduces the size of JavaScript and CSS files by removing unnecessary characters like white spaces, comments, etc.

• Bundling combines multiple JavaScript and CSS files into a single file to reduce the number of HTTP requests.

• This improves web application performance by reducing the load time of web pages.

• MVC provides built-in support for minification and bundling through the System....read more

Abstract class can have both abstract and non-abstract methods, while interface can only have abstract methods.

• Abstract class can have constructors, fields, and non-abstract methods.

• Interface can only have abstract methods and constants.

• A class can implement multiple interfaces but can only inherit from one abstract class.

• Abstract classes are used to provide a common base for multiple classes, while interfaces define a contract that implementing classes must follow.

Four OOP principles are encapsulation, inheritance, polymorphism, and abstraction.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Polymorphism: Ability of different classes to be treated as instances of a common superclass.

• Abstraction: Hides the complex implementation details and only shows the necessary features of an object.
