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.

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?
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?
