A diode presents a low resistance to current in one direction, and a high
resistance to current in the opposite direction. This property is used to
accomplish many different goals in various circuits. For example, it can
be used to extract DC from an AC power supply, and it can be used to
create new signals at frequency multiples of a pure signal.
The diode allows current flow in only one direction, from anode to cathode if you consider that current flows from positive to negative. In automotive use, a diode can allow one component to be powered from two different sources, while another component on one of the sources is only powered from that source. An example might be that you have two lights connected to each of two switches. Each switch controls one light. If you connect a diode between the two lights, then one switch can turn on both lights, but the other switch can only turn on one light. (Think turn signals versus brake lights, although this is often controlled by the switch instead.) Another very important automotive example is the six diodes in the alternator that form a three-phase full-wave bridge rectifier, converting the three phase AC stator voltage to DC to charge the battery.
A circuit board is the pathway for electrical currents to path through to send messages to other connectors. A circuit board consists of capacitors and resistors which allow and resist electric signals.
The most common purpose of a diode is to allow electricity to flow in only one direction :)
The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit. The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit.
A diode is an electronic component that will only allow current to flow through it in one direction. It is analogous to the valve in a bicycle tyre, which only lets air in but not out (except when you press the release tab). So if you connect a diode in a simple DC circuit one way around, the circuit will be closed and any devices on the circuit will work. If you connect it the other way around the circuit is open and no current will flow. I presume by 'ordinary diode' you mean a diode that is not a light emitting diode (LED). A LED is just a diode that emits light when current flows through it. Its purpose is to make light. A non-LED diode doesn't emit light. Its purpose is to allow current through a circuit in only one direction. A common use for ordinary diodes is in "rectifying circuits" which convert AC to DC.There are many other uses though.
The purpose of a diode is to direct the flow of current in a circuit. Diodes function by allowing current flow in only one direction (acting as a short when current is applied at one end) and resisting current flow from the opposite direction (acting as an open circuit). Electronic devices such as full wave rectifiers use a series of diodes to convert AC to DC current.
Purpose: An optocoupler (or optical isolator) uses optics to isolate one circuit from another. The diode in the optical isolator is similar to an LED. The light from this LED controls the gate or base of a transistor. A diode has two terminals, an optocouple will have at least 4. A diode is used to control current flow direction; an optocoupler main purpose is to isolate one circuit from another. etc. etc.
It is considered a diode, a Light Emitting Diode (LED).

Not sure of your context. A diode is a diode. One artificial distinction might be that an electric diode refers to a diode used in a higher power application with more current where an electronic diode might be found on a circuit board as part of an electronic lower power application.

If this is a question about a flywheel diode, it is there to prevent excessive voltage buildup when an electronic swich is opened, so if it is not working (open circuit) there is a chance of a further fault developing in the circuit.
No. The purpose of the zener diode is to clip (turn on) at a certain voltage. A capacitor will not exhibit this behavior.
An ordinary diode, no. It has nowhere to get energy from.But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.

An electronic component composed of two layers of a semiconductor material is a diode.

To avoid shocks and to avoid damage to the electronic gadgets
The main use of transistors in electronic circuits is as switches and memory storage
