There are a TON of great resources out there to help you get a better grasp of the two, even on YouTube! In ASD, the available strength is referred to as allowable strength, while in LRFD it is called design strength. The fundamental difference between LRFD and the allowable stress design method is, then, that the latter employs one factor (i.
