ROUTER
A device that connects any number of LANs. Routers use headers and a forwarding table to determine where packets go, and they use ICMP to communicate with each other and configure the best route between any two hosts.
Very little filtering of data is done through routers. Routers do not care about the type of data they handle
Ein Router ist ein OSI Schicht 3 Netzwerkgerät, das den Datenaustuasch zwischen LANs ermöglicht.
