What actions are performed when launching a Django application on a specific network port?

When launching a Django application on a specific network port, several key steps occur:

1. Django starts the built-in development web server (manage.py runserver) or an external server (e.g., Gunicorn), which listens on the specified port.
2. The server opens a socket and begins accepting incoming HTTP requests on that port.
3. Upon receiving a request, Django processes it through the URL routing system, determining the appropriate view.
4. The view executes the processing logic, interacts with models and templates.
5. An HTTP response is generated, which the server sends back to the client.

Example of starting the built-in server on port 8080:

python manage.py runserver 8080

Thus, specifying the port determines where exactly the application will be accessible to clients on the network.
