• In an asynchronous counter, each state is clocked by the same pulse.
• Asynchronous inputs will cause the flip-flop to respond immediately with regard to the clock input.
• A serial-in, serial-out shift register transfers data from one line of a parallel bus to another line one bit at a time.
• A parallel-in, serial-out shift register enters all data bits simultaneously and transfers them out one bit at a time.
