    Why we use clock in flip-flops?, also what is the meaning of synchronous and asynchronous?

    synchronous means that the system clock is ticking away at regular intervals and an input change happens, the logic will only recognize that a change happened when the system clock ticks and the flip/flop records (latches) the new value.

    Asynchronous is when the input happens and the logic knows immediately that something changed (like an AND gate) or comparator. The output is not Synchronized with a system clock.
