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.

What is difference between power diode and ordinary diode?
the High voltage rated diodes are power diodes while of low rating or normal voltage rating are considered to as ordinary / normal diode
IN5408 diode what does it do?
The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
What are the reverse characteristics of an led?
Unless the LED is a dual color LED, its reverse characteristics are similar to an ordinary diode.
What are the characteristic of photo diode?
A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. Its characteristics is same as that of an ordinary diode, except that it depends on light.
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.

Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.

The IN5408 diode is an ordinary silicon diode. It has a 3 amp forward current rating, and a 1000 volt peak reverse voltage rating.
Can a diode power a circuit?
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.
What is more energy efficient than ordinary backlighting?
Led (light emiting diode)
What are the reverse characteristics of an led?
Unless the LED is a dual color LED, its reverse characteristics are similar to an ordinary diode.

A photodiode is a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. Its characteristics is same as that of an ordinary diode, except that it depends on light.
Which side of diode is anode and which is cathode on the diode in a schematic?
The anode is the arrow shaped end, while the cathode is the bar shaped end. You can remember this by recalling that current flows from anode to cathode in an ordinary diode; well, that is, if you use the trick of assuming that current is hole flow, rather than electron flow, a useful and common convention. The exception, of course, is the zener diode, where current flows in both directions, but at different potentials. In this case, there are two 45 degree angled bars at the end of the cathode symbol, and the normal configuration of current flow is cathode to anode, backwards with respect to an ordinary diode.
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
How do a schottky diode and ordinary pn junction differ in their operation?
The schottky diode is based on a metal-semiconductor junction, called a schottky barrier, that results in lower forward voltage and vastly decreased switching time. While an ordinary silicon diode has a forward voltage around 0.7 volts, with a germanium diode around 0.3 volts, the schottky can be as low as 0.15 volts. The switching time can be in the tens of picoseconds range, compared to hundreds of nanoseconds. The downside is limited reverse voltage rating and poor reverse voltage leakage, which increases with temperature, causing potential thermal runaway.

Why diode conducts current in forward bias but does not conduct in reversed bias?
diode current flows only when the diode is forward biased because in reverse bias the barrier potential increases. Diode can conduct in reverse bias if applied votage is high enough to overcome the reverse bias barrier potential but it can be destructive.
