There is a world of difference: incremental programming means the control simply moves the machine to the next point relative to the present position. This can cause an accumulated error. It also makes starting in the middle of a program an impossibility.
Absolute programming reckons all movements relative to a datum or reference point on the part. Errors (due to rounding off) do not accumulate). Mid program starts are feasible if done carefully.
