Hubs vs Switches

| Hub | Switch | | —————————————- | —————————————- | | Broadcast to all devices connected to it | Broadcast to all devices connected to it | | Usually operates at half-duplex | Usually operates at half-duplex | | Sends information using frames | Sends information using frames |

Routers

Routes data between subnets, can also serve as the default gateway for traffic unrecognized within the network (connecting to the ISP’s box presumably to connect to the Internet). Most of our home routers also serve as switches. (So the difference between it and the switch is that it uses IP addresses to route data.)
