Either, they're really just without the vocals or they're modified to sound better as Instrumentals. But it's hard to tell sometimes, really. I never listen to them anyway though.
well sometimes they're different because they leave in little vocals for karaoke reasons. i think they should add "karaoke version" instead of instrumental or off vocal so it wont fool people.

There is accually a difference, from the different songs I've heard. Instrumental only has the Instruments (no, duh) while Off Vocal still has the background singers. Although, I haven't been able to find a difference between Off Vocal and Kareoke.
