In a standard diode, forward biasing occurs when the voltage across a diode permits the natural flow of current, whereas reverse biasing denotes a voltage across the diode in the opposite direction.

What is forward and reverse biasing?

A diode (PN junction) in an electrical circuit allows current to flow more easily in one direction than another. Forward biasing means putting a voltage across a diode that allows current to flow easily, while reverse biasing means putting a voltage across a diode in the opposite direction.

What is difference between forward and reverse bias?

Reverse bias increases a diode's resistance, and forward bias decreases a diode's resistance. A reverse bias does not permit the current to flow, whereas it flows effortlessly in forward bias through the diode.
