I am new to the world of networking and based on my readings there seems to be a definition of a 'true' router however am wanting to understand how do you tell if a router is a router? For example can I consider an off the shelf ADSL modem router a 'true' router? Does the OSI model matter when defining a router?
A router contains contains a series of software which allows multiple computers to access the same internet connection with ease. So as long as it allows multiple computer connections and forwards "packets" from the internet to the proper computer, it is considered a router.
Don't know what considers a "true" router, but an ADSL modem gives you the ability to interface with the connection protocol your ISP provides you, this being your WAN port (like most routers do), so I guess this is a "true" router.
Most OSI models are the same through consumer routers, in this case, it only matters in inter-connecting devices. In your case, you obviously cannot connect an Ethernet port to your WAN port, as the cables are different.

A router is defined by routing network data between two subnetworks, which every ADSL router does (internal network and carrier network).
