WAN

A WAN, or wide area network, is a computer network that links computers or smaller networks in different places over a large geographical area.

In plain English

It refers to networking across distance, between places that are far apart rather than all in one local area. The network joins computers, or whole smaller networks, that are in different locations.

In context

Here, WAN labels the router side that faces the larger outside network connecting different places over a wide area.

Situation
Installing broadband, activating service, using routers, and reading connection status
What it communicates
labels the router side that faces the provider connection.

Meaning limits

The term alone does not identify any particular outside network or the exact way the distant places are linked.

Examples

“Each clinic keeps its own local network, and a WAN links them across the region.”

Core meaning

“The modem connects to the router's WAN before the traffic reaches the office network.”
