6/14/2023 0 Comments Modem vs router vs firewall![]() ![]() The following video compares hubs, switches, and routers.Ī router is a more sophisticated device than a switch. Network hubs do not manage any traffic coming through them they only broadcast - or repeat - packets from an incoming port to all other ports. Network hubs - also called repeaters - are even less advanced that switches while a hub broadcasts the same data to all its ports, a network switch forwards data only to those devices that the data is intended for. A switch is considered a Layer 2 device, operating at the data link layer switches use packet switching to receive, process and forward data. Switches use MAC addresses to forward data to the correct destination. A switch is also called switching hub, bridging hub, or MAC bridge. ![]() Routers operate at Layer 3 (network layer) of the OSI model a router uses the destination IP address in a data packet to determine where to forward the packet.Ī network switch connects devices together on a single computer network. Routers are the workhorses that transfer packets of data between networks to establish and sustain communication between two nodes in an internetwork.
