REST framework supports HTTP content negotiation by providing a `Response` class which allows you to return content that can be rendered into multiple content types, depending on the client request.
The `Response` class subclasses Django's `SimpleTemplateResponse`. `Response` objects are initialised with data, which should consist of native python primatives. REST framework then uses standard HTTP content negotiation to determine how it should render the final response content.

There's no requirement for you to use the `Response` class, you can also return regular `HttpResponse` or `StreamingHttpResponse` objects from your views if required. Using the `Response` class simply provides a nicer interface for returning content-negotiated Web API responses, that can be rendered to multiple formats.
Unless you want to heavily customize REST framework for some reason, you should always use an `APIView` class or `@api_view` function for views that return `Response` objects. Doing so ensures that the view can perform content negotiation and select the appropriate renderer for the response, before it is returned from the view.

Unlike regular `HttpResponse` objects, you do not instantiate `Response` objects with rendered content. Instead you pass in unrendered data, which may consist of any Python primitives.
The renderers used by the `Response` class cannot natively handle complex datatypes such as Django model instances, so you need to serialize the data into primative datatypes before creating the `Response` object.

Serializers allow complex data such as querysets and model instances to be converted to native python datatypes that can then be easily rendered into `JSON`, `XML` or other content types. Serializers also provide deserialization, allowing parsed data to be converted back into complex types, after first validating the incoming data.

REST framework's serializers work very similarly to Django's `Form` and `ModelForm` classes. It provides a `Serializer` class which gives you a powerful, generic way to control the output of your responses, as well as a `ModelSerializer` class which provides a useful shortcut for creating serializers that deal with model instances and querysets.
