The gain in open loop is much much high, while this is not the case in closed loop. And yes, as emicho said. It is too.

@Shayaan_Mustafa just to complete your answer: if you use a negative feedback you have a gain lower than openloop gain, but if you use a positive feedback you have a gain higher than openloop gain (as in comparators with hysteresis)

This is usually in reference to amplifiers. Open loop gain is the intrinsic gain of the amplifier without feedback. Closed loop gain is the overall actual gain with feedback. Both the openloop gain and the feedback network need to be considered when designing for a target (closedloop) gain. Source(s): http://en.wikipedia.org/wiki/Operational…
