Question 7 of 22
A helpful analogy for a shift register is a conveyor belt. Examine this illustration showing a single conveyor belt at four different times, and determine which of the following shift register operations the sequence represents:
- Parallel-in, serial-out
- Parallel-in, parallel-out
- Serial-in, serial-out
- Serial-in, parallel-out

Reveal answerThis is a serial-in, parallel-out shift register analogy, with each box arriving on the conveyor belt one at a time, but leaving together as a group.
Notes:Some analogies can be very helpful to students as they learn new concepts. I have found that conveyor belts work very well to illustrate the different types of shift register behaviors.
