Django Basics

Django Fundamentals

• Python is the programming language commonly used with Django.
• The admin site in Django provides a convenient interface for managing models, allowing administrators to add, edit, and delete content without needing to write custom code.

Django Components

• ORM stands for Object-Relational Mapping, which is a system that allows Django to interact with databases using Python code rather than SQL.
• The Model in Django represents a database table, and is used to define the structure of the data and the logic for interacting with it.
• The Template in Django is a HTML file that defines the layout and appearance of a webpage, and can be used to display data from a model.

Networking Fundamentals

• Interoperability standards in networking allow different devices and systems to communicate with each other seamlessly.
• The two types of networks discussed are LAN (Local Area Network) and WAN (Wide Area Network).

Networking Models

• The OSI model consists of seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
• The TCP/IP model consists of four layers: Network Access, Internet, Transport, and Application.
• Protocol layering in networking enables data to be transmitted efficiently and reliably by breaking down the communication process into smaller, manageable tasks.
