You are probably referring to the steering. For many years power steering was accomplished by assisting the steering effort with hydraulic pressure. This hydraulic pressure is generated at the hyraulic pump commonly referred to as the power steering pump. Newer technology is to use an electric motor to provide the steering effort assist. This electric motor is part of the steering gear mechanism. The benefit of electric versus hydraulic is that the engine does not have to constantly spin a hydraulic pump and that saves energy and improves fuel mileage. Electric is more efficient and hydraulic is a long proven technology. I am not sure which one is better than the other.
