Question
In the figure below, assume each box is considered a node (not including thing1 and thing2). Suppose A is sending a packet to B. How many nodes in the network will look at the message and ask “is this for me?” if thing1 and thing2 are …
a. bridges? b. repeaters?
For the figure in problem above, suppose A is sending a packet to C. How many nodes in the network will receive the message if thing1 and thing2 are … a. bridges? b. repeaters?

How many nodes in the network will receive the message if thing1 and thing2 are a. bridges? b. repeaters?Explanation / Answer
A bridge is a device that connects and passes packets between two network segments that use the same communications protocol. Bridges operate at the data link layer (layer 2) of the OSI reference model. In digital communication systems, a repeater is a device that receives a digital signal on an electromagnetic or optical transmission medium and regenerates the signal along the next leg of the medium. Here in this example, if suppose A is sending packet to B then node C and another node in LAN1 will ask that is it for them?, after passing from a bridge then in LAN2, both the nodes will ask that is it for them. At last if the packet is not for nodes in LAN1 & in LAN2 then in LAN3 the repeater regerates the signal and all the the node checks for packet at last it goes to the B. Now if packet is to send from A to C, then first it checks for the destination in LAN1. And here C will respond it therefore, in this case only 2 nodes (C and other one) will ask that is it for them. Here there is no need of bridge and repeaters.
