Network device Description device that analyses packets of data transmitted from one network to another or analyses data within a single network gateway network point (node) that connects two networks that use different protocols switch device that connects LANS that use hub the same protocol to allow them to work as a single network device on a network that redirects data received to only those destinations on the LAN network that match the address in the data packet router device that sends all the received data packets to every device in the network irrespective of any data packet addresses bridge
