+# MVC or Model View Controller
+
+MVC or `Model View Controller` is a software design pattern commonly used for developing user interfaces that divides the related program logic into three interconnected components.
+
+Components:
+
+- `Model`: The internal representations of information. This can often be an Interactor or UseCase
+- `View`: The interface that presents information to and accepts it from the user
+- `Controller`: The controller contains logic that updates the model and/or view in response to input from the users of the app.

+# MVVM 
+
+The `Model-View-ViewModel` (MVVM) pattern is a software architectural pattern commonly used in UI development. It is designed to separate the concerns of an application, making the code more modular, testable, and maintainable.
+
+Components:
+
+- `Model`: Refers either to a domain model, which represents real state content (an object-oriented approach), or to the data access layer, which represents content.
+- `View`: The view is the structure, layout, and appearance of what a user sees on the screen.
+- `View model`: The view model is an abstraction of the view exposing public properties and commands. The view model has been described as a state of the data in the model.
