How to differentiate the roles between set-default and isolate?

[huyvl3-fptcloud]

I know the two objects to manipulate are graphical.target and multi-user.target. At the same time, set-default and isolate. So when should we use which function for which object? I can't imagine yet. For example:

1. systemctl set-default multi-user.target
2. systemctl set-default graphical.target
3. systemctl isolate multi-user.target
4. systemctl isolate graphical.target

What purposes will the above four commands serve?

Hello @huyvl3-fptcloud 

The difference between the commands is that command with "isolate" is executed immediately, and the command with "set-default" specifies the tagret system will get  after a reboot

Good luck
