Solution

Latches and flip-flops are basic building blocks of digital electronics systems used in computers, communications, and many other types of systems.

  1. Latches: Latches are level triggered. This means that the output of the latch changes as soon as its input changes. The latch remains in its state as long as the enabling signal is present.

  2. Flip-Flops: Flip-flops are edge triggered. This means that the output of the flip-flop changes only during the rising or falling edge of the clock signal. The most common types of flip-flops are D flip-flop, J-K flip-flop, T flip-flop, and S-R flip-flop.

In summary, the main difference between a latch and a flip-flop is that a latch checks input continuously and changes the output whenever there is a change in input, while a flip-flop is a latch that only changes its output when there is a rising or falling edge of the clock signal.
