Still a little confused about the 4 wheel drive setup

Ok, I understand the ESP and that it uses a BATCH (break assisted traction control) and I understand what that is and I understand that the nitro only has 4 wheel hi and open diifferentials - not limited slip and certainly not locking diffs...BUT, let's say, I cut off the ESP,

are all four wheels turning at once or just 1 in the front and 1 in the rear?

Thanks for putting up with my curiosity.
