1) Latch changes output with change of input but a flip flop only changes output during a clock pulse.Otherwise keeps existing values.
2) Sequential circuit is a circuit that is independent of current input and takes values based on clock pulses. Change in input doesnt effect output unless clock is high.
3) The D-type flip-flop is a modified Set-Reset flip-flop with the addition of an inverter to prevent the S and R inputs from being at the same logic level.
5) In many digital applications, it is desirable to limit the responsiveness of flip flop to shorter period of time instead of entire duration of active enable input.
