    Sounds dangerously like homework.

    Why the homework is dangerous?

    Probably dangerous because the OP is risking his ability to learn by not researching, or thinking critically about it, and simply asking for the answer.

    @OP, in what cases might a flip flop lose the bit stored?

    Well, to be fair, the title of the thread is "Homework Help". I agree with most though. As an old friend was given to reply to such a question, "What's the book say?"

    All that being said, a flip-flop maintains its state until the input condition (that sets the output) is changed. As far as temp or permanent, if you want a given output to be permanent, why would you use a flip-flop?

    You go to a book or go to AAC- what is the difference? You learn in either case [ both may be wrong or right, you have to decide ].
    There are volatile and non volitile memories [ FFs]; a magnetically latched relay or magnetic core can be an example of a non-volitle memory, FF.
    Power operated FF devices , IC FFs, 555, relay, can be considered volitle FFs, [ post # 6 ].
    An alarm system is reset- green board- all secure. Window breaks generating a set signal to FF[ memory] causing an alarm, Red board.

    Don't forget: reading course materials, be that textbook or lecture notes.

    Not researching, so many people did that, so I can imagine it, but thinking critically about it, do you have any example?

    I'd consider that research.... Having a question and going elsewhere to find the answer is a skill everyone needs to have.

    Thinking critically was hinted at with my question to the OP.

    One of the ways a flip flop loses the bit stored is at a power loss. If the flip flop losses the bit when power is removed from the system, is it permanent?

    Researching could lead to an understanding that a flip flop is comprised of a series of gates. Does a gate retain its ability to operate once per is removed? No, it doesn't. If the things making up the flip flop don't work at a power loss, is the flip flop permanent, nonvolatile storage?

    One who learns by finding out, has seven fold the skills of him who learns by being told.
