Bridges supply a simple implies for connecting LANs. A bridge is a device that connects physically separate LAN segments (such as different Ethernet cables) into a single logical LAN segment. There are four categories of bridges: transparent, source routing, encapsulating, and translating. Transparent bridges are employed for Ethernet, whereas supply routing bridges are employed for token ring networks. Encapsulating bridges connect two segments of the exact same media (such as token ring to token ring) over a medium. The getting bridge removes the envelope, checks the destination, and sends the frame to the location device. Translating bridges are employed to connect various sorts of network media such as Ethernet and FDDI (fiber distributed information interface). FDDI is a set of protocols that makes use of a modified kind of the token-passing method over fiber-optic cable.
A network switch is a device that forwards and filters OSI layer two datagrams ( frames ) between ports based on the destination MAC address in every frame. 17 A switch is distinct from a hub in that it only forwards the frames to the physical ports involved in the communication rather than all ports connected. It can be thought of as a multi-port bridge. 18 It learns to associate physical ports to MAC addresses by examining the supply addresses of received frames. If an unknown location is … Read More
