How does Artisan::call and Artisan::queue work?

Hi guys I trying to understand Artisan::call and Artisan::queue here . Im still have no idea how its work and why does Artisal::queue different instead of just calling Artisan::call..

I've try to make a custom command then I call it from controller and I get same result either I call Artisan::call or Artisan::queue. should I call dispatch(new SendArtisanCommand); so inside SendArtisanCommand I call Artisan::queue ?

can someone explaind when to use Artisan::call or Artisan::queue
