In a shift register, what happens to the bit shifted off the end?
It is recycled back to the input
It is saved internally
It is stored in a buffer
It is lost unless saved externally
What is the function of the control input in some shift registers?
To enable parallel loading
To reset the register
To allow bidirectional shifting
To increase the clock speed
How can n bits of data be loaded into a shift register in one clock cycle?
Using a buffer
Using a faster clock
Using parallel inputs
Using serial input
What is one of the important applications of shift register circuits?
Data encryption
Serial computation
Parallel computation
Signal amplification

In a serial adder, what is the role of the D flip-flop?
To store the sum
To store the clock pulse
To store the input data
To store the carry out
What is the first step in performing addition using a serial adder?
Shift the addend into register B
Clear registers A and B, and the D flip-flop
Run the adder for eight cycles
Load the sum into register A
What is the purpose of the 74164 shift registers in the serial adder?
To store the binary numbers to be added
To store the clock pulses
To store the carry
To store the sum
What is the output of the full adder during the initial clock cycles when registers A and B contain all zeroes?
0 for sum and 1 for carry
