Define
Shift Register . Explain a 4 bit SISO shift
register.
​

Answer 1

Answer:

A shift register is a type of digital circuit using a cascade of flip flops where the output of one flip-flop is connected to the input of the next. ... Data was stored into the array and read back out in parallel, often as a computer word, while each bit was stored serially in the shift registers.

The SISO shift register is one of the simplest of the four configurations as it has only three connections, the serial input (SI) which determines what enters the left hand flip-flop, the serial output (SO) which is taken from the output of the right hand flip-flop and the sequencing clock signal (Clk).
