Routers are responsible for 'route' determination for packets. **Additional information: Routers work at the layer 3 of the OSI model and can route packets from one network to another (LAN to LAN, or LAN to WAN). Switches work at the layer 2 of the OSI model and do packet switching to receive, process and forward packets on a LAN. Hubs and Repeaters work at the layer 1 of the OSI model and do not manage any network traffic.
