 1. Copy module: Copies files from the control machine to the target host. like deploying a configuration file. 2. Package module: Irrespective of the operating system, it selects the appropriate package module and installs, upgrades, or removes software. 3. Service module: manages services like start, stop, restart, enable 4. User module: Manages user accounts like create, deleting, and modifying user accounts 5. yum/apt module: Install or remove upgrade packages like Debian-based and red hat based environments.

How Ansible Modules Work Execution Flow: whenever  y ou execute a playbook or run an ad-hoc command 2. Ansible copies the module to the target host 3. The module executes on the remote system 4. Results are returned to the Ansible control node
