It is a semiconductor device with two terminals, typically allowing the flow of current in one direction only. It may also be termed as the electronic component with two electrodes known as the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. The diode acts as a valve in the electronic and electrical circuit.

yes, diode can be used as rectifier diode to convert ac to dc

To test an ordinary semiconductor diode use a multimeter to verify that it conducts in one direction but not in the other. Testing of other types of diodes (e.g. zener diode, tunnel diode, gunn diode, Peltier heat pump diode, photodiode, PIN diode, varactor diode, light emitting diode, LASER diode, vacuum tube diode) is more complicated and often requires special test equipment unique to that type of diode.

A diode is a device that allows current to flow through it in only one direction. A semiconductor diode is a diode that is created with solid state technology. Contrast this with the vacuum tube diode.

whether we know that p-n diode is real diode. But still in case of semeconductor we see then silics is real diode.

Normal Diode works in Forward Bias and Zener Diode works in reverse bias region.

The primary difference is that a semiconductor diode is a diode with a p-n junction, and a light-emitting diode is a special case or special type of semiconductor diode that emits light when it is forward biased.

Its not, a diode is unidirectional.

zener diode is a revers bias diode which used for voltage regulation.

when the diode temperature increases conductivity of diode gets increases

The 1N4007 diode is a 1000V diode, while the 1N4005 is a 600V diode. Both diodes have a 1A rating.

Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.

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.
