Correct Answer : Flip Flop
In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information.A flip-flop stores a single bit (binary digit) of data; one of its two states represents a “one” and the other represents a “zero”. Such data storage can be used for storage of state, and such a circuit is described as sequential logic. When used in a finite state machine, the output and next state depend not only on its current input, but also on its current state.
