IIR filters have nonlinear phase characteristic which means the output of such a filter is (most likely) a deformed version of the input without the filtered frequency. On the other hand IIR filters might become unstable. So IIR filters are used, when the user is not particularly interested in the output in time-domain but only in frequency-domain, e.g. in audio applications such as speakers...

Difference between FIR and IIR filters?
1)The impulse response of an IIR filter extends over infinite duration while the impulse response of FIR filter is stricted to finite no. of samples. 2)IIR is not always stable but FIR is always stable. 3)FIR can have precisely linear phase while IIR filters do not have linear phase.

Explain the advantages and disadvantages of FIR filters compared to IIR counterparts?
IIR filters are recursive and FIR filters are non-recursive. Also FIR filters are linear phase and IIR filters are not; several applications are sensitive to non-linear phase (communications, medical, etc). In implementation, IIR filters require fewer taps (smaller order) and thusly are easier to implement and have fewer zeros. Also FIR filters are always stable, while IIR filters can often become unstable in implementation. The previous answer is correct about delays.
Where is the IIR filter used?
IIR Filter is one of the Digital Filters .it is used mostly in Audio Signals Processing

Difference beyween IIR and FIR filters?
The impulse response of an IIR filter extends over infinite duration while the impulse response of FIR filter is stricted to finite no. of samples. Also IIR is not always stable but FIR is always stable.
What does it mean if a digital filter is IIR?
We can divide filters two types based on the length of the impulse resopnse 1. FIR where the impulse responce is finite 2. IIR where the impulse response is infinite
