A "layover" is a term you will hear from novices when they describe a connection (e.g., "I had a three hour layover in Atlanta on my way to San Francisco"). I don't think it is anything more than a connection as it relates to airline rules.
I understand a connection to be the need to change planes, and a "layover" to be the duration of time you have in between flights when connecting ("stopover" if above the maximum allowed time to be considered a "layover" - 4h domestic/24h international). Pull up any itinerary with a connection on DL.com and expand the details; you will see Delta say "Layover in Cincinnati, OH (CVG) 1h 38m"
