sum of smaller 2 sides is greater than the other one which is larger

Linear LAN architecture in which transmissions from network stations propagate the length of the medium and are received by all other stations. Compare with ring topology, star topology, and tree topology.

BUS topology and STAR topology

In a packet-switched star topology, a router that is part of the backbone and that serves as the single pipe through which all traffic from peripheral networks must pass on its way to other peripheral networks.

(This indicates you want to be a star, as well.)

There are three basic configurations used with SONET: Point-to-Point, Hub (Star), and Ring

There are five topologies for networks -> Ring Topology -> Star Topology. -> Bus Topology. -> Mess Topology. -> Hybrid Topology.

-> Very orderly network where every device has access to the token and the
   opportunity to transmit . -> Performs better than a star topology under heavy network load .
-> Can create much larger network using Token Ring.
-> less cost than star network.
