Weather Forecasting Computer-aided design try to predict weather, taking data from sensors, using computer models of weather systems (CAD) designs for objects can be designed, altered and tested within the computer, prior to manufacture Monitoring And Control Systems A computer is used to monitor a system through the use of sensors (such as light, heat, etc.) The computer can then operate devices to control the system (such as pumps, valves, etc.) Monitoring hospital patients checks heart rate, etc. setting off an alarm if low Nuclear power station control monitors temperature, etc. and adjusts coolant Traffic survey and control checks the number of cars, alters traffic light timings Automation And Robotics The use of computers to control other mechanical devices. Usually requires some sort of interface which allows the computer to receive data from input sensors, and to control output devices such as motors.
