Explanation: The JK Flip-Flop Definition: A JK flip-flop is a type of digital storage element (or bistable multivibrator) that can operate in various modes, such as set, reset, toggle, or no change, depending on the states of its inputs (J and K) and the clock pulse. It is similar to the SR (Set-Reset) flip-flop but resolves the ambiguity when both inputs are high. The JK flip-flop is widely used in digital circuits due to its versatility and ability to handle the "race condition" present in SR flip-flops.
