What part of a packet radio frame contains the routing and handling information?
- A.Directory
- B.Preamble
- C.Header (correct answer)
- D.Trailer
WhyThe header of a packet radio frame contains the routing and handling information. A packet radio frame's header carries the addressing and routing information, source and destination callsigns and control fields, that tells the network how to handle and deliver the frame, answer C. "Directory" isn't a packet frame section, the preamble is used for synchronization rather than routing, and the trailer typically carries error-checking data rather than routing information, so A, B, and D are wrong.
