star topology

• In a star topology, each computer system is connected to a central node (hub)
• Advantages of a star topology:

  • Improved security as data packets are sent directly to and from the central hub/switch
  • New systems can be attached directly to the central system without network shutdown
  • Fast transfer speeds with minimal network collisions
• Disadvantages of a star topology:

  • Extra hardware (hub or switch) is required and needs maintenance
  • If the central system fails, the whole network becomes unusable until fixed
