Transistor biasing is a function of implementing a DC support circuit that places the transistor in an electrical region that produces the desired output signal in relation to its input signal, according to its design specification. A transistor can be biased to create a linear amplified signal proportional to its input. Biasing can also place the transistor into an easily saturated condition to propagate clipped binary output relative to its input. Biasing refers to the component configuration designed around a specific transistor family. Connection refers to the simple function of making an electrical junction between two conductors.

Why is it necessary to bias a transistor when it is to be used as an amplifier?
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail

What is difference between transistor and bias?
"Biasing" applies to transistor amplifier circuits. Simple amplifier circuits can only amplify positive signals. Negative signals cause the amplifier to shut down. However, AC signals in general have both a positive and a negative part. To allow a transistor to amplify AC, we add a positive voltage to the AC signal. Then after it is amplified, we remove the positive voltage again. The voltage, ac or dc on the base, compared to the emitter to cause operation of the transistor to conduct to the collector or to the emiiter in a NPN transistor.
Why are 2 batteries needed for biasing a transistor?
They aren't, it can and is done just fine with one.
What is emitter biasing?
Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.

What are the biasing roles of transistor?
A: Transistor to be effective as an linear amplifier it must be operated in its linear load range. The biasing scheme is to insure that the transistor is put in its linear/load range
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.
What are operating point int transistor biasing?
A: An operating in biasing is determined by the transistor capabilities as a linear amplifier. Basically it is a bias to insure linear operation with the loading of the output
