Gi)
Biasing is needed so that thermal runaway cannot take place.
Biasing is done to operate BJT in saturation region.
Fixed Bias circuit has very high stability factor so it is highly stable biasing circuit.

h-parameters represent input resistance and output conductance when output is
shorted.
h-parameters represent forward voltage gain and reverse current gain of BJT at certain
conditions.
Input resistance of CE amplifier is high compared to CB amplifier.
Output conductance of CC amplifier is high compared to CB amplifier.
