BUS NETWORK TOPOLOGYRING NETWORK TOPOLOGYSTAR NETWORK TOPOLOGY
A bus network consist of a single central cable to which all computers and other devices connectA cable formed a closed loop with all computers and devices arranged along the ringAll the computers and other devices on the network connect to a central device , thus forming a star

Advantages;
  • failure of one device does not  affect other devices
  • bus networks are inexpensive and easy to install
Disadvantages;
  • the network will be malfunction if the single cable break down
  • difficult to identify the problem if the entire network shut down

Advantages;
  • All computers have equals access to the resources in the network
  • cable faults are easily located, making troubleshooting easier
Disadvantages;
  • the network will malfunctioned if the device or cable break down
  • \a ring network can span a larger distance than a bus network, but it is more difficult to install

Advantages;
  • if one device fails, only thet device is affected
  • easy to troubleshoot and isolate problem
Disadvantages;
  • the network will be malfunctioned if the single hub/switch break down
  • requires more cable than most of the other network topology
