 '''Diagram 1:''' In this situation, server has sent a broadcast to the network. Each workstation receives a copy. 

 

+Related to Broadcast, Multicast is simply a broadcast where the data packet is not sent back to the source port. Where a hub broadcasts, a switch multicasts. For example, OSPF Designated routers multicast link state advertisements to all other OSPF routers in the area using the multicast address of 224.0.0.5.

+On the other hand, a unicast is simply transfer from one source to a single destination.

 It appears from my quick readings that we have: 

- * Ethernet broadcast 

+ * Ethernet broadcast 

  * Limited broadcast 

  * Directed broadcast 

 It may be worth expanding each of these into their own subsection, especially as we are dealing with multiple subnets in our network.
