DATA LINK PROTOCOL AND COMMUNICATION NETWORKS
Similar to wide-area networks, local-area networks are an example of communication networks interconnecting several devices for information exchange. The LAN design is usually for a single floor or building, but it can also reach to multiple buildings via routers and bridges. The design is shared medium rather than switching nodes. The internal data rates for LANs are greater than for wide-area networks.

Design a system of three LANs with four bridges. The bridges (B1 to B4) connect the LANs as shown below. Show diagram in Word and use any diagramming tool to demonstrate the design (Forouzan 2007, p.465).
B1 connects LAN 1 and LAN 2.
B2 connects LAN 1 and LAN 3.
B3 connects LAN 2 and LAN 3.
B4 connects LAN 1, LAN 2, and LAN 3.
Can we replace the bridge with a router? Explain the consequences.
Which one has more overhead, a bridge or a router? Explain your answer.
Which one has more overhead, a repeater or a bridge? Explain your answer.
Which one has more overhead, a router or a gateway? Explain your answer.
