The resonance is the condition where we get maximum value of the amplitude and in RLC circuit when the impedance is minimum at a particular frequency then we get maximum amplitude and that frequency is known as resonant frequency.

Bandwidth is the difference of half part frequencies and can be obtained from the graph and quality factor is the ratio of resonant frequency and bandwidth.
