🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) equipment and modern radio technology on ships • How digital and computer-controlled systems can replace traditional, single‑purpose radios • The difference between a radio type and a measuring instrument like an SWR meter

💭 Think About

• Which option describes a kind of radio system that can change its function or frequency range by using software instead of changing hardware? • On a vessel, would an SDR be more likely to be a communication device, a test instrument, or a type of computer memory? Why? • Which choices sound like they belong to marine communications, and which sound more like general electronics or computing terms?

✅ Before You Answer

• Verify which option clearly names a radio rather than a meter or memory device • Check which term is commonly used in modern digital and programmable radio systems, especially in GMDSS or other marine comms • Make sure the choice you pick could realistically appear in a ship’s radio room or integrated bridge system as primary communications gear
