Logic circuits

What is a typical use of a shift register, which chains flip-flops in series and moves data one bit to the next on each clock?

  2. BOscillation
  3. CConverting between serial and parallel data
Show answer and explanation

Answer: C. Converting between serial and parallel data

A shift register can collect data arriving one bit at a time on a single line (serial) and output it all at once in parallel, or do the reverse. It is used in communication interfaces and in the scan chains of scan testing.
