### Explanation of CRC Operation: Polynomial Division, Shift Register, and Comparison (video)

Here is a video explaining the mechanics of Cyclic Redundancy Check computations, including: An example of the polynomial division approach An example of the XOR-feedback shift register approach A step-by-step comparison of how the polynomial division and shift register approaches are actually doing exactly the same computation. If you've ever wondered why it is that a shift register and polynomial division end up with the same result, this video explains it. Video links (27 minutes): YouTube | Archive.org
