What is the difference between gate and latch in digital electronics?

The difference between a latch and a flip-flop is that a latch does not have a clock signal, whereas a flip-flop always does.

Apart from the clock signal difference,

~ Latch is a level sensitive device while flip-flop is an edge sensitive device.

~ Latch is sensitive to glitches on enable pin, whereas flip-flop is immune to glitches.

~ Latches take less gates (also less power) to implement than flip-flops.

~ Latches are faster than flip-flops.
