A router acts as a junction between two or more networks to transfer data packets among them. [...]

[...] Routers connect networks together the way that on-ramps or major intersections connect streets to both highways and freeways, etc. The street signs at the intersection (routing table) show which way the packets need to flow.

So for example, a router at home [or at a hotspot or hotzone venue] connects the Internet Service Provider's (ISP) network (usually on an Internet address) together with the LAN in the home [or at the hotspot or hotzone venue] (typically using a range of private IP addresses, see network address translation) and a single broadcast domain.
