Latch and Flip-Flop
The latch and flip-flop are the basic memory element that stores 1-bit ( 0 or 1) of information.
Since the output of these memory elements has two stable states ( 0 or 1), they are also known as a bi-stable multivibrator.

Difference Between Latch and Flip-Flop:

The Latch is a level-sensitive memory element. It responds to the input level change immediately.
sometimes it is also known as a transparent latch (because it responds to the change in input immediately)

The transparent latch with the control input / enable input is known as the Gated Latch. This type of latch becomes transparent when the enable input is high.

Although Latch behaves as an Asynchronous memory element, it can be used as a Synchronous memory element by applying the periodic clock signal at the control / enable input.
In this case, still it is level sensitive. Because it responds to the change in the input when the clock signal / enable input is high. And in this way, it is sensitive to the clock signal level.

The flip-flop is an edge-sensitive memory element. It responds to the input at the clock transitions.
If the flip-flop responds to the input at the rising edge of the clock then it is called a positive edge-triggered flip-flop. And if the flip-flop responds at the falling edge of the clock then it is called a negative edge-triggered flip-flop.

In this video, the difference between the latch and flip-flop is explained using the timing diagram.

This video will be helpful to all the students of science and engineering in understanding what is Latch and Flip-Flop, and what is the difference between Latch and Flip-flop.
