The following table lists several common connection devices used within a LAN. Device Description Hub A hub is the central connecting point of a physical star, logical bus topology. Hubs manage communication among hosts using the following method: 1. A host sends a frame to another host through the hub. 2. The hub duplicates the frame and sends it to every host connected to the hub. 3. The host to which the frame is addressed accepts the frame. Every other host ignores the frame. Hubs are Layer 1 devices; they simply repeat incoming frames without examining the MAC address in the frame. Bridge A bridge is a device that connects two (or more) media segments on the same subnet, and filters traffic between both segments based on the MAC address in the frame. A bridge builds a database based on MAC addresses to make forwarding decisions. The process begins by examining the source MAC address of an incoming frame. If the source address is not in the forwarding database, an entry for the address is made in the database
