    What is the main difference between a serial-in/serial-out shift register and a serial-in/parallel-out shift register?

    <p>Serial-in/parallel-out shift registers allow all stored bits to be accessed simultaneously, while serial-in/serial-out shift registers only allow one bit to be accessed at a time.</p> Signup and view all the answers

    How are the J and K inputs of a JK flip-flop connected in a typical 4-bit shift register implementation?

    <p>The non-inverting output Q of one flip-flop is connected to the J input of the next flip-flop, and the inverting output Q' is connected to the K input.</p> Signup and view all the answers

    What is the main advantage of a serial-in/parallel-out shift register over a serial-in/serial-out shift register?
