MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -A bistable memory elements used in sequential circuits to store binary information are called flip-flops. A flip-flop is a binary cell capable of storing one bit of information. It has two outputs, one for the normal value and one for the compliment value of the bit stored in it.

Detailed explanation-2: -The memory cell is the fundamental building block of computer memory. The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level).

Detailed explanation-3: -A Flip-flop is a clock-controlled memory device. It differs from a Latch in that it has a control signal (CLOCK) input. It stores the input state and outputs the stored state only in response to the CLOCK signal.

Detailed explanation-4: -Statement (I): A basic memory unit of a flip-flop is a bistable multivibrator. Statement (II): A flip-flop has two stable states. It remains in one state until it is directed by an input signal to switch over.

Detailed explanation-5: -There are four basic types of flip-flops. They are: Latch or Set-Reset (SR) flip-flop. JK flip-flop.
