Question

Which one is false

• A. shift registers operate in serial fashion one bit at a time
• B. parallel processing techniques are economically feasible
• C. register with parallel load operate with all the bits of the word simultaneously
• D. all of the above are true

Answer 1

Answer: (D)

all of the above are true

All the options are true.

Shift registers operate in serial fashion one bit at a time:-

A shift register is a cascade of flip flops, sharing the same clock, in which the output of each flip-flop is connected to the 'data' input of the next flip-flop in the chain, resulting in a circuit that shifts by one position the 'bit array’ stored in it, 'shifting in' the data present at its input and 'shifting out' the last bit in the array, at each transition of the clock input.

Parallel processing techniques are economically feasible:-

Parallel processingis a method of simultaneously breaking up and running program tasks on multiple microprocessors, thereby reducing processing time. Parallel processing may be accomplished via a computer with two or more processors or via a computer network.

Register with parallel load operate with all the bits of the word simultaneously:-

A shift register is used to move data to the left or to the right by one bit for each input clock pulse. Parallel load means to load all flip-flops of a register at one time.
