Network Topology

Network Topology

1. Star Topology

   • All nodes are connected to each other through a switch
   • Advantages
     • Failure of one node does not affect other nodes
     • New nodes can be connected easily
     • Communications are passed to recipient only
     • Less data collisions
   • Disadvantages
     • Whole network is down if the switch goes down
     • Wired star networks are expensive- lots of devices attatched

2. Topology is an arrangement by which all the nodes are connected

3. Mesh Topology

   • No central nodes, all devices are connected to each other
   • Advantages
     • Communications recieved quicker
     • Communications can always get through
     • No nodes will become isolated
     • Each node can transmit to and receive from more than one node
   • Disadvantages
     • More connections means more maintenance
     • More expensive
   • Partial mesh topology is where most of the nodes are connected to each other but not every single one to every single one
