Switching hub
A network connection box to which a number of computers can be connected. The
switching hub forwards a data packet from the network to the appropriate computer
according to the packet’s address. Conventional hubs simply send every packet to every
connected computer. Since a switching hub forwards packets only to their intended
recipients, it provides greater efficiency.
