What is a flip-flop? What is the difference between a latch and a flip-flop? List out the application of flip-flop.
Ans. Flip-Flop: It is a fundamental memory element utilized to store one bit of information. Both latches and Flip-flops are bistable logic circuits and can reside into any of the two stable states because of a feedback arrangement. The major difference among them is in the method utilized for changing the state.
Applications of Flop-Flops:
1. Bounce elimination switch
2. Parallel Data Storage in Registers
3. Transfer of Data from one bit to another.
4. Counters
5. Frequency Division
