diode
의미: A semiconductor device that allows electrical current to flow in one direction only. Light-emitting diodes (LEDs) produce light when current passes through them.
Diodes are essential components in electronics, used for rectifying alternating current (converting it to direct current), protecting circuits from reverse voltage, and regulating voltage. The most familiar type to the general public is the LED (light-emitting diode), which has largely replaced incandescent bulbs for lighting. Photodiodes detect light and are used in solar cells and optical sensors. The 'di-' prefix refers to the two terminals: anode and cathode.
