Topologys

Topologys

1. Star

   • very reliable – if one device fails then all the others will continue to work
     • if a hub or switch fails all the devices connected to it will have no network connection
   • high performing as no data collisions can occur
   • expensive to install
   • extra hardware required

2. Mesh

   • very expensive
   • very reliabale
   • if one node fail's the server can continue to work
   • Set-up and maintenance of this topology is very difficult

3. bus

4. partial mesh

   • point-to-point link
   • It is robust
     • A fault is diagnosed easily

5. ring

   • This type of network can transfer data quickly
     • data only flows in one direction
     • If the main cable fails or any device is faulty then the whole network will fail
   • won’t be any data collisions.
