Biasing is used in a transistor amplifier circuit in order to place the transistor as nearly as possible in the center of its linear region. Transistors have cutoff, linear, and saturation regions. Too little bias current, and you enter cutoff - Too much, and you saturate. Both conditions cause distortion when you attempt to use the transistor as an amplifier, as opposed to a switch.

What is the forward biasing of a junction?

Forward biasing can be satisfied when a positive polarity of a battery connect with P side and the negative connect with N side In the P-N junction, that is caused : The free electrons in the N side will pushed by negative charge, and holes move far of positive charge, after that we will have a barrier (small area of barrier between P and N) this biasing called Forward biasing, because of small resistance of barrier, the current will flow, we can use it as a switch. the Reverse biasing is the opesit of all these specifications.

What is meant by biasing and explain all the baises?

It means that a voltage is established between two of the three terminals of a transistor, to achieve the desired operation. Since with three terminals you can choose three different combinations of two terminals, there are three different types of biasing.The details vary, depending on the type of transistor used. Also, the details are quite involved. The Wikipedia has some introductory articles; for example the article on "Biasing", or on "Bipolar transistor biasing" if you want to know about biasing for this specific type of transistor.
