Router


A router (not to be confused with a bridge) is a data network device that transfers data from one LAN to another. Routers can be hardware- or software-based, though larger applications and faster communication speeds all but require a hardware router. Routers are used in homes and offices with high-speed internet access such as DSL; they serve to connect the local LAN to the high-speed WAN operated by a service provider.
