Venu,
If you really want to get technical about it....
Bypass caps are used to eliminate (short out) resistors during ac
operation. An example would be to bypass an emitter resistor in order
to increase the voltage gain of an amplifier.
Coupling caps are used to block the direct current, but still allow ac
signal to pass. An example would be to couple multiple stages of an
amplifier.
However, they are basically performing the same operation

Craig
