What is a split level floor plan?

A split level floor plan is a home with more than 1 level and instead of traditional 2 story home with an upstairs being approximately 9 feet above the downstairs - a split level home will have a 2nd or 3rd story but they are just 4.5 feet above the first floor..so just 6 or so steps.
