Q

What is a common method used to program radios without using a “wired” connection?

🔍 Key Concepts

• Common short-range wireless data links used in consumer electronics (e.g., TV remotes, older phones, some radios) • How line‑of‑sight light-based communication can transfer data between two nearby devices • Which technologies in the options actually exist in practical radio servicing

💭 Think About

• Look at each option and ask: does this technology really exist and is it used in everyday devices for short‑range data transfer? • Think about what kind of invisible light is commonly used in remote controls for TVs and stereos—does any option match that? • Which option sounds like science fiction or made‑up terminology versus a real, known method?

✅ Before You Answer

• Identify which choices describe a real, currently used technology versus something that seems invented for the question • Recall that most short‑range, light‑based remote controls use a specific part of the spectrum, not ultraviolet • Eliminate any option that would require global satellite involvement for simple local programming tasks
