What are the various topology of WAN and what is the drawback in BUS topology?
there are a few different topologies when you are talking about
WAN's but remember WAN's topologies are different than LAN's
because of the area they cover. But there are bus wan, ring wan,
star wan, full mesh wan, partial mesh wan, and tiered wan.
as far as a drawback to bus topology is that each site in the
wan bus topolgy depends on every other site in the network to
transmit and receive its traffic.
