There's two standard jump stops within the rule book definition.
1. Ball gathered with both feet in the air, one foot down and jump once to land on both feet. Legal, but neither foot may be put back down once lifted before passing, shooting, or calling a timeout. This is more typical with a drive to the basket.
2. Ball gathered with one foot on the floor, jump and land on both feet. Legal with the same restrictions as above. I see this more often with jump shooters on the perimeter (especially around the three point line) and used to call it traveling. Man I was wrong.
