• Module - units of code providing a narrow functionality (e.g. the yum module installs packages using the yum package manager).
• Task - execution of one module with a set of arguments.
• Playbook - set of tasks in YAML.
• Role - set of playbooks to be run on a group of hosts.
• Host - a machine that Ansible will configure through SSH.
• Inventory - definition of the hosts and variables to be used in the playbooks.
