LAN verses WAN port, what is the difference?

The recent connection to fixed-wireless nbn, .. bring attention to this question, what is the difference? – Asking the Internet this question duckduckgo search.?

SOME BASICs – LANs tend to use Ethernet and Token Ring, WANs use technologies like MPLS, ATM, Frame Relay and X.25 for connectivity over longer distances.

The links provided compare important differences in the hardware, and describe the protocols used within ‘a network‘.

This Router_vs_Switch comparision provide useful insight – QUOTE; – “Routers connect two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router. The term layer 3 switch often is used interchangeably with router, but switch is really a general term without a rigorous technical definition. In marketing usage, it is generally optimized for Ethernet LAN interfaces and may not have other physical interface types.” [End quote]

The osi model(s) will describe the Router as Network Layer 3 devices, and a Switch as a Data Link Layer. Network switches operate at Layer 2 of the OSI model.
