The temperature in a glasshouse is controlled by a computer. A program is being designed to open and close the glasshouse windows. If the temperature is too hot, then the windows will open; otherwise the windows will close. The systems analyst has produced a number of different instructions to show how the system works. Part of the instructions are shown. Complete the instructions by writing the most appropriate technical terms to explain how the windows are operated. • Data is read by the sensor. • data is output from the sensor. • Data from the sensor is sent to the microprocessor via the • If the temperature is greater than the • The microprocessor sends a signal to the Circle the two most appropriate input devices associated with the computerised glasshouse. Chip and PIN reader Hard Disk Drive Laser printer LED monitor Moisture sensor Numeric keypad Another use of computer control is in the manufacture of cars. Discuss the benefits and drawbacks of using computer-controlled systems rather than humans to build a car.
