Can you discuss UDS & KWP2000 protocols and how they differ?

When asked a question that uses acronyms or terminology specific to the job, make sure you understand what the interviewer is asking about and the type of answer they are expecting from you. If you do not understand any part of the question, it is appropriate to ask a clarifying question. It is better to do this than to answer the question incorrectly because you misunderstood it or were unfamiliar with the interviewer's terminology. You can accomplish the same thing by inserting a qualifier in your answer.

"By UDS, I assume you mean Unified Diagnostic Service Protocol. KWP 2000 refers to the keyword protocol standard. Both of these address standards within the transmission of data in CAN. UDS addresses event triggering and periodic data transmission, involving measurement values using two-byte identifiers. KWP2000 employs both a one-byte record local identifier and a two-byte common identifier."
