When not changing state.

D flip-flop
The "RS" in RS flip flop stands for "Reset-Set". The RS flip flop has a Reset and a Set input. You can reset or set the flip flop as desired. Output state will be held based on whichever input was last asserted.
Replace the T input by sbar rbar q bar + sbar r q
Race-around condition is arises in level triggered JK flip flop . when you apply 1 to both j and k input than the flip flop will toggle on every clock or it may toggle multiple times in the same clock pulse . it may be possible that new output will feedback to input before clock goes to zero (for positive edge triggered) if it happens than the flip flop will toggle on time again . this undesired toggling is called Race-around condition. overcome by - using edge triggered flip flop. using very narrow clock width.
toggle condition :- the condition of the flip-flop in which on the application of clock-pulse inverts the present state Q(t+1) = Q'(t) on the application of clock-pulse for JK-flip-flop the toggle condition is J=K=1 for JK flip-flop this is called toggle condition condition
The JK in JK flip flop stands for Jack Kilby who was the inventor of JK flip flop.His complete name was Jack St. Clair Kilby.
A flip-flop is called a basic memory cell because its logic operation has the hold mode.
Digital memory consist register which are the collection of flip flop and can be accessed easily. When we want to store the data on digital format than apply the data to flip flop(D flip flop) and it is set or rest or hold 1 or 0 as you applied and store it on the flip flop.
can intestant flip flop
It isn't, which is the problem.
by using master slave flip flop
In a master-slave flip-flip arrangement, the master flip-flop determines its state on one clock edge, while the slave flip-flop determines its state on the following clock edge. This way, the end-to-end output does not ever change on any one clock edge, so no race condition is possible.
