The bridge has three ports. A is connected to bridge port 1, B is connected to bridge port 2, C is connected to bridge port 3. A sends a frame addressed to B to the bridge. The bridge examines the source address of the frame and creates an address and port number entry for host A in its forwarding table. The bridge examines the destination ...
A physical topology that contains switching or bridge loops is attractive for redundancy reasons, yet a switched network must not have loops. The solution is to allow physical loops, but create a loop-free logical topology using link aggregation, shortest path bridging, spanning tree protocol or TRILL on the network switches.
With the Java bridge, CFStrings were instead cast into Java's own String objects, which required more work but made porting essentially invisible. [3] Other developers made widespread use of similar technologies to provide support for other languages, including the "peering" system used to allow Obj-C code to call .NET code under Mono. [4]
A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ports.
Switches for Ethernet are the most common form of network switch. The first MAC Bridge [3] [4] [5] was invented [6] in 1983 by Mark Kempf, an engineer in the Networking Advanced Development group of Digital Equipment Corporation. The first 2 port Bridge product (LANBridge 100) was introduced by that company shortly after.
Network administrators can see networks from both physical and logical perspectives. The physical perspective involves geographic locations, physical cabling, and the network elements (e.g., routers, bridges and application-layer gateways) that interconnect via the transmission media.

Collisions are localized to the physical-layer network segment they occur on. Thus, the broadcast domain is the entire inter-connected layer-2 network, and the segments connected to each switch or bridge port are each a collision domain. To clarify; repeaters do not divide collision domains but switches do.
