Q74 / 100

What is the difference between a "SIPO" and a "PISO" shift register?

Correct! Well done.

Incorrect.

The correct answer is A) A SIPO (Serial-In Parallel-Out) shift register accepts data one bit at a time and makes all stored bits available simultaneously on parallel outputs; a PISO (Parallel-In Serial-Out) register loads all bits at once and shifts them out one bit at a time

A

Correct Answer

A SIPO (Serial-In Parallel-Out) shift register accepts data one bit at a time and makes all stored bits available simultaneously on parallel outputs; a PISO (Parallel-In Serial-Out) register loads all bits at once and shifts them out one bit at a time

Explanation

SIPO registers are often used to convert a serial data stream into parallel form (e.g., for driving multiple LEDs from one data line), while PISO registers convert parallel data into a serial stream (e.g., for transmitting data over a single wire).
