What is a flip-flop circuit?
- A A binary sequential logic element with eight stable states
- B A binary sequential logic element with four stable states
- C A binary sequential logic element with one stable state
- D A binary sequential logic element with two stable states
Correct answer: D — A binary sequential logic element with two stable states. From the official ISED question bank, verified word for word.
Why
A flip-flop is a simple electronic switch that holds one of two possible conditions, such as on or off, making it a binary element with exactly two stable states. The full explanation — and one for every question — is in Pro.
