15. Describe the three basic subsystems in a computer control system.
1. Sensor subsystem check various operating conditions using sensors. The sensing system sends different electrical current values back to the control module.
2. Control subsystem looks at the inputs from the sensors and determines what actions need to take place. Then the control momudle provides signals to the actuator subsystem.
3. Actuator subsystem serves as the hands of the computer system. The actuators turn on or off, open or close, or change position based on the signals from the control module.
