Advantages and disadvantages of bus topology

Bus topology is one of the best and simplest network topology, it is also known as a linear topology. It is easy to connect the computer, It consists of a computer that is attached to a common cable so it is very simple and flexible. This article gives information about the advantages and disadvantages of bus topology to know more details about it.

Advantages of bus topology :
  • Easy to connect a computer
  • Easy to implement and extend
  • Suitable for small network
  • It is flexible and scalable
  • It is very simple and easy to install
  • Require less cable length than a star topology
  • It is less expensive
  • If one node fails, other nodes are not to be affected
  • When a node added or removed to and from the network, the network is not affected
  • Typically to cheapest topology to implement
Disadvantages of bus topology :
  • Entire network fail is there any problem in a central cable
  • Difficult to administrator and troubleshoot
  • Limited cable length and number of station
  • Performance degrades as additional computers are added
  • Maintenance cost may be much higher in the long run
  • A cable break can disable the entire network, and there is no redundancy
  • Every work station all the data on the network (security issues)
  • Used to connect 5 - 9 system only
  • One virus in the network will affect all of the systems
  • If many computers are attached, the amount of data flowing causes the network to suddenly slow down
  • Proper termination is required
  • The efficiency of the bus network reduces, at that time as the number of devices connected to it increases
  • Data traffic is high
  • Data collision is high
