The structure of the calculator:
A calculator is generally composed of arithmetic unit, controller, memory, keyboard, display, power supply, and some optional peripheral equipment and electronic accessories, which are composed of manual or mechanical equipment. The arithmetic unit and controller of the low-end calculator are realized by the digital logic circuit for simple serial operation, and the random access memory has only one or two units for accumulative storage. High-end calculators are implemented by microprocessors and read-only memory for various complex calculation programs, and there are more random storage units to store input programs and data. The keyboard is the input part of the calculator, and generally adopts the contact type or the sensor type. To reduce the size of the calculator, one key often has multiple functions. The display is the output part of the calculator, such as a light-emitting diode display or a liquid crystal display. Integrated circuit (see complementary metal-oxide-semiconductor integrated circuit), and is equipped with an automatic power-off circuit when it is not operated. The peripherals available for the calculator include micro printers, cassette tape drives, and magnetic card players.
