Diode
General diodes are made up of Si gerally and we operate this diodes generally in forward bias while Zener diode in the reverse bias . Is there any difference in the construction of this two diode i.e. I want 2 say why we use Zener diode only in the forward bias ?

your question is excellent the basic difference between the zener and normal one is the amount of doping in it the normal will have impurity as1:10^8 and in zener it will have as 1:10^5 so in the forward bias the zener and normal are similar so the properties of the zener as voltage regulator can be found in the reverse bias mode only so we prefer the zener to normal one in the reverse bias
