Router
A router is a network component that links
several computer networks. Router ana-
lyses (on the basis of layer 3 information)
the network packages of a protocol it re-
ceives and forwards it to the intended des-
tination network. Conventional routers work
on layer 3 of the application layer. A router
has an interface for every network connec-
ted to it. When data is received, the router
determines the correct path to the destina-
tion and thereby the suitable interface via
which the data can be transferred. For this
it uses a locally available routing table that
specifies via which router connection a par-
ticular network can be reached.
