What is meant By Transistor biasing

Semiconductor transistor usually has two junctions between p and n regions. The terminals Base, Emitter and Collector are connected to the external circuit. The terminal which controls the switch (flow of current or no flow of current) is given a voltage above the threshold voltage. Then current flows through the transistor.
Example common Emitter transistor configuration, has biasing at the base terminal. So when voltage is applied at the base, current flows through collector, base and emitter. Otherwise, no current flows.

helloo!!
To fix the operating point at the middle of active region a dc voltage is provided... it prevent the signal swing below cut off.
Necesary of Biasing:
1)To fix the operating point at the middle of active region.
2)stabilize the collector current aganist temperature varrions.
hope this helps
