Question 1 of 27070

Which statement best defines the SITOR (NBDP) acronym "ARQ"?

🔍 Key Concepts

• SITOR (NBDP) operating modes: ARQ vs FEC • The meaning of the letters in ARQ (Automatic Repeat reQuest) and what that implies about traffic direction (one‑way vs two‑way) • Difference between broadcasts (many receivers, one transmitter) and direct TELEX links (two specific stations)

💭 Think About

• Ask yourself: If the system is requesting repeats of errored data, does that require a return path from the receiving station, or can it work in pure one-way transmission? • Consider which type of traffic needs all stations to copy the same message at the same time (like weather/nav broadcasts) versus which type is an interactive link between two stations. • Look at which choices mention TELEX vs telephone; which mode is SITOR (NBDP) primarily associated with?

✅ Before You Answer

• Verify which SITOR mode (ARQ or FEC) is used for broadcasts such as weather and navigation warnings. • Check whether ARQ needs "2 stations in direct" communication or can work for a one-way transmission only. • Confirm that the correct option refers to TELEX data rather than voice/telephone.
