Network topologies

• Bus network


  Advantages:

  • Quick to set up – well suited for temporary networks
  • Cost-effective – less cabling

  Disadvantages:

  • Low security – all computers on the bus can see all data transmissions
  • If there is a problem with the main cable or connection, the entire network goes down

  
• Ring network


  Advantages:

  • It prevents network collisions
  • The transmission of data is relatively simple as data packets travel in one direction only

  Disadvantages:

  • If any of the computer systems fail, the ring is broken and data cannot be transmitted efficiently
  • If there is a problem with the main cable or connection, the entire network goes down

  
• Star network 


  Advantages:

  • Good performance/fast network speed
  • Easy to set up

  Disadvantages:

  • Expensive to install – more cabling required
  • Extra hardware required, such as a hub

  
• Mesh network 


  Advantages:

  • Mesh topologies can withstand high traffic
  • If one node fails, there is always an alternative present

  Disadvantages:

  • Cabling costs are high
  • Administration of the network is difficult
