Latches are LevelSensitive, while Flip-Flops are EdgeSensitive.
A positive level latch is transparent to the positive level(enable), and it lathes the final input before it is changing its level(i.e. before enable goes to '0' or before the clock goes to -ve level.
A positive edge flop will have its output effective when the clock input changes from '0' to '1' state ('1' to '0' for negedge flop) only.

Latch is a level triggered device but flip flop is a edge triggered device.
Latch takes less gates but flipflop takes more.
Latch faster, flipflop
slower.
Latch does'nt have a clock signal but flip flop depends on the
clock signal, but both are having one bit memory.

Latch doesn't need any clock signal. But for flip flop we apply the clock.

Latch is level sensitive whereas flip flop is edge sensitive.latch has no clock signal but flip flop has. Latch is asynchronous sequential circuit but flip flop is synchronous.FLIP flop IS SYNCHRONOUS VERSION OF latch.Latch is made from gates but Flip Flop is made up of Latches.Latch is A temporary buffer but Flip Flop is a 1 bit storage element.

well latch is a monostable,level triggered & flip flop is bistable ,edge triggered

They both have 2 stable states (bistable) to store data.
They are diffrent in the way they change their states.

flipflop : these are edge triggered devices and clock signal is required and also it is having two values.
latches: these are level triggered devices and clock signal is not required and it is having only one value.

Latchesand flip flops are similar, both are bi-stable logic circuit, i.e two stable state. It can reside in any of the two stable states due to arrangement. The main difference between them is in the method used for changing states.
Basically latche uses level trigger and fllip flops uses edge triggered.

LATCH:
The latches are nothing but most basic types of flip-flops.
the latches are level sensitive whereas flip-flops are edge sensitive.
Thus the change of state in a latch will occur even for an active high input (dc level) i.e., the latch will respond to the change in state when the clock pulse is still in logic1 which will lead to undesirable situation.
The change of state in a flip-flop occurs only when their is a change in the clock input.
Since the state of a memory element must change only there is a change in control input (ac level)
FLIP FLOPS:
we use flip-flops as storage elements in digital circuits instead of latches.
it is EDGE TRIGGERED DIVICE.
it is bistable

Latches do not have clock signal as input, while flip flops do.
