Latches and Flip Flops

Latches and flip flops are elements wherein the output depends not only on the current inputs, but also depends on the previous state of inputs and outputs. The main difference between a latch and a flip flop is that a flip flop has a clock signal, whereas a latch does not. There are different variations of latches and flip flops: SR, D, JK and T. The major differences between these types of flip flops and latches are the number and types of inputs they have and how they change of state.
