Rails active vs action (Railties naming) [duplicate]

Question

Railties in Rails are named starting either with active or action:

• action mailer
• action pack
• action view
• active job
• active model
• active record
• active support

What's the difference between active and action, and what do these words have to do with component's contents or functionality?

Answer 1

Action names represents the controller layer (and the view layer), responsible for handling incoming HTTP requests and providing a suitable response.

Active names represents the model layer. Represents your domain model and encapsulates the business logic that is specific to your application.
