Terminology
Any FBW system will have an inceptor (control) which provides a control signal into the AFCS (Automatic flight control system) which is a negative feeback loop (more likely a complex multiple loop with rate integration incorporated) into which is also fed rate / position sensor information from control position / aircraft position / rate of change data. The output is a function of the input control signal and the feedback data, and designed to keep the aircraft at whatever condition is required by the main input signal (specific heading, airspeed, attitude, etc.).
This is universal. However, in what order the black boxes are arranged to achieve this, and exactly what sensors or inceptors are used will vary a lot. This is where the difference in company terminology comes in.
