🔍 Key Concepts

• Difference between a local area network (LAN) and a wide area network (WAN) in terms of physical distance and coverage • How wired vs wireless connections are typically shown in diagrams (solid lines, antennas, radio waves, etc.) • What point-to-point wiring looks like compared to multiple devices sharing a common network through a hub or similar device

💭 Think About

• Look closely at how the PLCs and PC workstations are all linked together in figure C: are they connected directly one-to-one, or do they share a common network path through another device? • Ask yourself whether this drawing suggests short-range communication within the same space (like an engine room or control room) or long-distance links between separate facilities or ships. • Check the diagram for any indication of radio/antenna symbols versus solid cable runs—what does that tell you about whether it is wired or wireless?

✅ Before You Answer

• Confirm whether there is a hub or central device shown that multiple units plug into, which is typical of a LAN. • Verify that the connecting paths appear as solid cables rather than any wireless symbol, which would rule out a wireless network. • Decide if the network appears limited to a single local area (same plant/ship) or spread over a large geographical area (which would indicate a WAN).
