Concept
Job has only existed within the terminal window that started it.
Job can consist of multiple processes linked together (e.g., a pipeline).
A Linux service (like sshd for remote access, nginx for web serving, or systemd itself) is a process, but it is never a job.
Because these processes don't have controlling terminal.
