What is a Flip-Flop?
A
a 2 state device which offers basic memory for sequential logic operations, heavily used in banks called “registers”
B
a logic device used to invert a value
C
a storage device that works with non binary numbers
D
None of the above
Explanation: 

Detailed explanation-1: -"Flip-flop” is the common name given to two-state devices which offer basic memory for sequential logic operations. Flip-flops are heavily used for digital data storage and transfer and are commonly used in banks called “registers” for the storage of binary numerical data. signal.

Detailed explanation-2: -In electronics, flip-flops and latches are circuits that have two stable states that can store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will output its state (often along with its logical complement too).

Detailed explanation-3: -Flip flop is a sequential circuit which generally samples its inputs and changes its outputs only at particular instants of time and not continuously.

Detailed explanation-4: -Flip-flops are the basic piece of sequential logic. They effectively store a single binary digit of state. There are a variety of flip-flops available that differ on how that state is manipulated. Since a flip-flop stores a binary digit it must, by definition, have 2 states.

Detailed explanation-5: -Flip-Flop : Flip-flop is a basic digital memory circuit, which stores one bit of information. Flip flops are the fundamental blocks of most sequential circuits. It is also known as a bistable multivibrator or a binary or one-bit memory. Flip-flops are used as memory elements in sequential circuit.
