Django is a high-level web framework written in Python that follows the Model-View-Controller (MVC) architectural pattern. It provides a set of tools and libraries for building web applications quickly and efficiently.

Django is a full-featured web framework that provides a lot of built-in functionalities and follows a batteries-included approach. Flask, on the other hand, is a micro web framework that is minimalistic and provides only the essentials for building web applications.

Some advantages of using Django include its scalability, security features, built-in administrative interface (Django Admin), object-relational mapping (ORM), template engine, and support for various databases.

ORM stands for Object-Relational Mapping. Django's ORM maps database tables to Python objects and provides an abstraction layer for database operations. It allows developers to interact with the database using Python code instead of writing raw SQL queries.

A Django model is a Python class that represents a database table. It defines the structure of the table and includes fields and methods to manipulate the data. Models are used in Django to interact with the database.

A Django view is a Python function or class that takes a web request and returns a web response. Views define the logic for handling different URLs and generating dynamic content to be displayed in the browser.

A Django template is a text file that defines the structure and layout of a web page. It can contain HTML markup with placeholders for dynamic content. Django's template engine processes the template and replaces the placeholders with actual values.

The Django admin site is a built-in feature that provides a user-friendly interface for managing and interacting with the data in the database. It automatically generates a CRUD (Create, Read, Update, Delete) interface based on the model definitions.

Django migrations are used to manage changes in the database schema over time. They allow you to create, modify, and apply database schema changes without losing existing data. Migrations are created based on the changes in Django models.

Django forms are used to handle user input and data validation. They provide a convenient way to define HTML forms, handle form submission, and perform validation on the submitted data.

The Django REST framework is a powerful extension to Django that allows you to build RESTful APIs quickly and easily. It provides tools and libraries for handling API requests, serialization, authentication, and more.

Django middleware is a component that sits between the web server and the view. It allows you to process the request and response globally across all views. Middleware can perform tasks like authentication, request processing, and response modification.

The Django URLconf is a module that maps URLs to views. It contains a set of patterns and corresponding view functions or classes. The URLconf defines the URL structure of a Django application.

Django signals are used to allow decoupled applications to get notified when certain actions occur elsewhere in the application. Signals are used for implementing certain cross-application functionalities and can be used for various purposes.

The Django template language is a domain-specific language (DSL) used to define dynamic content in Django templates. It provides constructs for variables, loops, conditionals, filters, and more.

The Django context is a dictionary-like object that stores variables and their values. It provides data to the templates for rendering dynamic content. Context can be passed to templates from views or middleware.

Django apps are self-contained modules that encapsulate a specific functionality or a set of related functionalities. Apps can be plugged into Django projects to add specific features or extend the project's capabilities.

The Django testing framework is a set of tools and utilities provided by Django for writing and executing tests. It allows developers to write unit tests, integration tests, and functional tests for Django applications.

Django's Object-Relational Mapping (ORM) is a technique that allows developers to interact with the database using Python objects instead of writing raw SQL queries. The ORM maps database tables to Python classes and provides an abstraction layer for database operations.

Django's authentication system provides a secure way to manage user authentication and authorization. It includes features like user registration, login, logout, password reset, and user permissions.
