Network Topologies

           Networks can be laid out in a number of different ways. The physical layout of a network is called its topology. The basic network topologies are Star, Ring, Bus. These basic topologies can be combined in a variety of ways to build complex hybrid network topologies.

Star Topology

           In a star network all computers and other communications devices are connected to a central point such as a hub, file sever or a host computer.

Ring Topology

            In a ring network all communications devices are connected in a continuous ring. Messages are passed around the ring until they reach the right destination.

Bus Topology

           In a bus network communications devices are connected to a common channel. There is no central computer and the communications devices transmit message to the other devices.
