What are some of the differences between CAN Data Frames & Remote Frames?

When asked to compare two technologies, the easiest way to structure your answer is to define each of the technologies first and then discuss their similarities and differences. Developing frameworks for answering specific types of questions will enable you to focus on the answer and not how you will structure it during the interview. This will also make your answers more consistent throughout the interview and demonstrate your ability to organize information while performing this job.

"There are several differences between CAN data frames and remote frames. The first is that the data field only exists in the data frame. Another key difference is that the RTR is a recessive bit in the remote frame and is set to 1, while in the data frame, it is a dominant bit set to 0. This comes into play when several transmitters are attempting to use the bus simultaneously and arbitration as required. Priority is given to the dominant bit."
