How is variable storage implemented and managed in Ansible?

In Ansible, variables are stored and managed using several mechanisms, each with different priorities and scopes:

• Inventory variables — variables defined in inventory files for hosts or groups.
• Playbook variables — variables set directly in the playbook or in tasks.
• Facts — automatically collected data about hosts during execution (e.g., IP, OS).
• Registered variables — results of task executions that can be saved and used later.
• Variable files — separate YAML files with variables that can be included.

Ansible manages variables through a priority system where variables with higher priority override those with lower priority. This allows flexible environment configuration and overriding values when necessary.
