Communication Protocols — question 7 of 10

Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.

Recall that in CAN, a dominant bit (0) always overwrites a recessive bit (1) when both are driven simultaneously, and lower numeric identifier value generally means higher priority.

Two CAN nodes start transmitting at exactly the same time. Node A's 11-bit identifier is 0x1A3, and Node B's is 0x1A5. Walk through the arbitration process bit by bit and tell me which node wins and keeps transmitting, and why. Then explain: if this bus is missing its 120-ohm termination resistor at one end, what symptom would you actually expect to see, and under what bus conditions would it show up?

How sure are you?

Being confidently wrong costs more mastery than admitting a guess — that is deliberate, and it is how misconceptions get found.

Neither is graded, and nothing here is recorded.
