0 Bridge comes in three basic types

Local bridges

Directly connect local area networks (LAN)

Remote bridges: Can be used to create wide area network (WAN) link between the LAN. Remote bridge, where the link connecting the slower end of the network, most have been replaced with the router.

Wireless bridges: Can be used to combine LAN or LAN to connect remote stations


Switches


A network switch is a device that filters and advanced OSI layer 2 datagrams (deduction data communications) between ports (connected cables) based on the address on the package in March. This is different from a hub in that it only continue to port the packages involved in the communication of all connected ports. Precisely, a switch capable of routing traffic is not based on IP address (OSI Layer 3) is required to communicate between network segments or in large or complex LAN. Some can switch routing based on IP address but still called switches as a marketing term. A switch typically has many ports, the purpose is that most or all network connected directly to a switch, button or other in turn linked to a saklar.


Switch is a marketing term that encompasses routers and bridges, and devices that can distribute the traffic load on the content or application (for example, a Web URL identifier). Switch can operate in one or more layers of OSI model, including physical, data link, network, or transport (ie, end-to-end). Devices that operate simultaneously in more than one layer is called MultiLayer switch


Too stressed that ill-defined term often shift causing confusion when first trying to understand the network. Many experienced network designers and suppliers sarankan start dealing with the logic device with only one protocol level, not all covered by OSI. MultiLayer selection tool is advanced topics that can lead to selecting particular implementations, but MultiLayer switching not only the real world design concept.


Routers


A router is a network device proceed package information using the network protocol headers and forwarding tables to determine the next router is best for each package. Router to work on the Network Layer OSI model layer of the Internet and TCP / IP.
