Task 3 :

Difference between command systemctl vs service

• service: A traditional command used in older Linux distributions with the System V init system. It manages services by starting, stopping, restarting, enabling, or disabling them.

• systemctl: A modern and more powerful command used in newer Linux distributions with the systemd init system. It also manages services but offers more advanced features, including service dependencies, control groups, and better integration with the system.

In general, if you're using a newer Linux distribution, it's recommended to use systemctl as it provides more capabilities and is the standard method for managing services.
