Advantage and Disadvantage of Bus Network

A network layout where one trunk cable provides the main path of communications. Each node is then connected to this common cable. This common cable also known as “Backbone”

In this type of arrangement the ends of the cables must have terminators installed to complete the circuit and devises are attached to the Drop lines or taps. This type of topology is very poor at handling cable problems as all of the stations beyond the affected area will be brought down.

Bus Network Advantages:
  • Ease of installation
  • Low cabling requirements

Bus Network Disadvantages:

  • Difficult to reconfigure nodes.
  • Fault isolation is difficult.
  • Too many connections to the backbone can seriously degrade performance.
  • A fault in the bus cable causes the whole network to be disabled.
