I suspect you don't mean " serial cable" - i.e: DE-9 (aka DB-9): but if you're talking about this, then you're not talking about IP / Routing / X Area Networks. In some industries RS-485 is used for point to multi-point networking (with a specific master). We don't use these terms to describe logical configuration (i.e: " two routers connected with a serial cable")Īdditionally, a " serial cable" implies RS-232 (possibly RS-422), and isn't really considered to be " networking" within the in modern definition - it's used all over the place for configuration and direct interfacing. Note how these terms are all tied to the physical configuration and size of a network. Wide Area Network implies even further afield - for example, " the Internet".Metropolitan Area Network implies a larger network - a neighbourhood for example.Local Area Network implies " in the same building".Until you tell us about the physical layout of your hypothetical network, we can't use terms like LAN / WAN / etc. Two routers connected with a serial cable are just that - two routers connected with a serial cable.
