1: A light pen is a pointing device that is used to select objects on a computer screen by detecting light emitted by the screen, while a stylus is a pen-like tool used for writing or drawing on a touchscreen device.
2: Magnetic ink character recognition (MICR) is a technology used to read characters printed with magnetic ink, typically used for processing checks, while optical mark recognition (OMR) is a technology used to detect marks made on paper, such as in standardized tests or surveys.

1: Light Pen and Stylus
- Light Pen: A pointing device that uses a light-emitting diode (LED) to detect objects on a screen. When the pen's tip touches the screen, it emits light and the computer determines the position by measuring the intensity of the reflected light.
- Stylus: A pen-like device with a conductive or capacitive tip that interacts with touchscreen devices. It allows users to write, draw, and navigate the interface without using their fingers.
2: Magnetic Ink Character Recognition (MICR) and Optical Mark Recognition (OMR)
- MICR: A technology that uses magnetic ink to encode characters on documents. Magnetic ink contains iron oxide particles and can be read by magnetic sensors in specialized devices. It is commonly used for check processing and other banking applications.
- OMR: A technology that uses optical sensors to detect marks made on paper. OMR devices can read marks such as bubbles, circles, or checkboxes to collect data from surveys, exams, and other forms.
