Hub contains multiple ports. When the package arrives at a port, it is copied unchanged to all ports hub for the transfer. Destination address in the box does not change the broadcast address.

A network bridge connects multiple network segments in the layer data link (layer 2) of the OSI model. Bridges not promiscuous copy traffic to all ports, as hubs, but to know the MAC addresses are reachable through specific ports. Since the members of a bridge of a port and an address, it will send traffic to this address only to that port. Bridges send broadcasts to all ports, except that where the transmission was received.
Bridges learn the association of ports and addresses by examining the source address of frames that can be seen in various ports. Once a picture is through a gate, the source address is stored and the bridge assumes that MAC address is connected to that port. The first time that an unknown destination address is seen above, the bridge of the frame to all ports other than the frame arrived.
Bridges come in three basic types:
1. Local bridges: Directly connect local area networks (LANs)
2. Remote bridges: Can be used in a Wide Area Network (WAN) to create connections between local networks. Remote bridges, where the connection is slower than the networks finals, largely been replaced by routers.
3. Wireless bridges: Can be used to enter or LAN to LAN connect external drives

A network ahead and change filters in a device layer of the OSI data communication between the ports 2 datagrams (block) () in packets based on MAC addresses to connect the cables. [6] This is different than an input port just forward all ports connected to the appropriate packages instead contact. Obviously, the IP address (OSI Layer 3) that a network for communication between the LAN segments or large or complex state routing traffic based on the necessary, but will be a transition. Some switches based on IP addresses is a marketing term orientation as a talented, but still passed. Normally this switch, most or all of the network directly connected to a switch to another switch or delivery, depending on the transition has a large number of ports. [7]
Switches, routers and bridges, and distribute the traffic load or application content (eg a Web URL identifier) devices is a marketing term. Switches one or more (that is, from beginning to end) physical, data link, network or transport layers, including the OSI model, can operate. Multiple layers of activity at the same time that a device called a multi-layer switch.
Bad “key” is defined in terms that try to understand the first network Overemphasizing often leads to confusion. Many experienced network designers and operators, equipment not related to only one protocol level, each with a logic that are covered by OSI recommended starting. Multilayer device selection by the selection of the applications in question could lead to an advanced topic, but it is not only a multi-layer switching, real-world design concept.
