Network Topologies.

A network topology is the physical layout of network. Basically the way all the nodes in the network are connected. There are several different types of network topologies, each with advantages and disadvantages. The different types of network topologies are Bus topology, Ring topology, Star topology and Mesh topology.

Bus topology.


The first type of network topology is called a bus topology. A bus topology uses one cable to connect all of the nodes together. A bus topology is very easy to set up and requires no additional hardware. The cable is also called a backbone or trunk. The bus topology is probably the easiest one to understand and to implement. Bus topology networks use coaxial cable. Each end of each segment of the network has a special cable terminator on it, without which the network will not function.


Advantages.

  • It’s easy to install and maintain.
  • It’s inexpensive to implement.
  • No additional hardware required, such as switches and hubs.
  • Less cabling is required than other topologies.

Disadvantages.

  • One breakdown of cable is affect to the whole network.
  • Difficult to troubleshooting.
  • Data communication is slower than with some of the other topologies.
