OCR Computer Science 1.3 Network & Topologies

1. Star Topology

   • Simultaneous access
     • The star topology is beneficial as it means that lots of devices can access the server at the same time.
   • Reliability
     • If a single client fails, then all other clients can continue as usual. But, the whole network will be affected if the server fails.
   • Scalable
     • The network can easily be scaled up by adding more devices.
   • Expensive
     • It can be expensive to run a cable to every single device in a wired star. Wireless star networks can sometimes be more cost effective.
