A network switch is a device that forwards and filters OSI layer 2 datagrams (frames) between ports based on the destination MAC address in each frame. A hub is a network device that repeats all incoming data packets to all ports. A switch is more intelligent than a hub, as it can forward data to the specific port it is intended for, instead of broadcasting it to all ports. Additionally, a switch can provide additional features such as VLANs, Spanning Tree Protocol (STP), link aggregation, and Quality of Service (QoS).
