• systemd is an init system commonly used in distros like Linux Mint, Arch, Manjaro, Ubuntu, Debian, etc.

• init systems have a process id of 1 and manage services like a login manager, network, firewall service, etc.

• a process id is assigned to every process in a linux system.

the average user usually doesn’t worry about the init system, although more experienced/techy users may care about it.
