Network Topologies

Network Topologies

1. Ring

   • Each packet of data on the network travels in one direction
   • ADVANTAGES
     • this type of network can transfer data quickly, even if there are a large number of connected devices. This is because the data only fowls in one direction, so there won't be any data collisions
   • DISADVANTAGES
     • if the main cable fails or any device is faulty the the whole network will fail

2. Bus

   • ADVANTAGES
     • more reliable than a ring network as if one workstation breaks not all of them will
   • this is where all nodes are connected to a main wiren called a bus
   • DISADVANTAGES
     • more expensive than ring network
     • if the main wire breaks all the workstations will

3. Star

   • All nodes on this network are connected to a central hub
   • ADVANTAGES
     • if a cable fails it will only affect one workstation
     • more computers can be added without disruption
     • easy to identify problems
   • DISADVANTAGES
     • expensive
     • failure of central computer will stop the network from working

4. Mesh

   • all nodes are connected to one another
   • ADAVANTAGES
     • can withstand high traffic
     • data can be transmitted from different devices simultaneously
     • if one of the components fail there's another alternative available
     • provides security
   • DISADVANTAGES
     • expensive
     • complicated set up
