Latches and flip-flops are the basic elements for storing information. One latch or flip-flop can store one bit of
information. The main difference between latches and flip-flops is that for latches, their outputs are constantly
affected by their inputs as long as the enable signal is asserted. In other words, when they are enabled, their content
changes immediately when their inputs change. Flip-flops, on the other hand, have their content change only either
at the rising or falling edge of the enable signal. This enable signal is usually the controlling clock signal. After the
rising or falling edge of the clock, the flip-flop content remains constant even if the input changes.
