hi,
A "bridge" in computer lingo is used to inter-connect any two networks.
The bridge has information regarding the IP addresses (or computers) connected to it. It allows network traffic outside the home network only when it receives a request for connecting a IP address which is not on the home network. In this way, local traffic is kept within the network and bridge filters the traffic which are meant outside the network.
A typical example is a bridge connected between a LAN in an office and a WAN (Internet).
Happy programming!
Regards,
Vidhya

Bridge is used to connect two networks using different protocols. Bridge checks the MAC addresses contained in the frame. A bridge has filtering capability. It can check the destination address of a frame and decide if the frame should be forwarded or dropped. If the frame is to be forwarded, the decision must specify the port. A bridge has a table that maps addresses to ports. This table is used in filtering decisions.
In order to reduce the traffic, bridge must be installed between two networks.
Traffic consideration is must because the frame may be discarded when the traffic is overflow. Bridge is installed between two networks in order to reduce the traffic.
