Definition of RouterA Router is a device that connects two
networks - frequently over large distances. It understands one
or more network protocols, such as IP or IPX. A Router accepts
packets on at least two network interfaces, and forwards packets
from one interface to another. Router's may be programmed to
filter out some packets, and to dynamically change the route by
which packets are routed. Router's often use different media on
each interface. For instance, a router might have one Ethernet
port and one ISDN port.
