In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information. [...] Flip-flops and latches are used as data storage elements. Such data storage can be used for storage of state, and such a circuit is described as sequential logic.

What are these states in Flip-flops?
I know that DRAM-storage makes use of capacitors. The two states are: Either the capacitor is charged or not. But I have no idea how to imagine the state of Flip-flops. What changes in the flip-flop if the state changes?
I am not a physicist, so please keep your answer as simple as possible.
