- A switch, as opposed to a hub, that connects nodes or segments in a LAN. A LAN switch enables all nodes to have the entire bandwidth available, up to 100 Mbps for each in the case of fast Ethernet, for instance, as opposed to all nodes having to share the bandwidth, as would be the case when a hub is used. Also called frame switch.
- A device in a LAN that selects a path or circuit via which data will flow to its next destination. Such a switch usually involves a simpler and faster mechanism than a router, but may also have router functions.
