STAR TOPOLOGY, MESH AND RING TOPOLOGY







STAR TOPOLOGY
All cable segments connected to a center hub with p2p.
All transmission is done through hub
Hub acts as repeater too.
Was familiar in mainframe computers.
Simplest topology to implement.
Advantage: easy to add new nodes.
Disadvantage : single point of failure.











Ring.
Single circle network
No terminated ends
Each computer acts as repeater.
More reliable than pure star network
Each computer is transmitter and receiver too.
One node stop means all stop after that node.



Ring Topology






Mesh
All nodes are interconnected by dedicated lines to all others.
Highly reliable ease of installation.
Very costly and redundant.

Used in conjunction with others to make hybrid technology.
