Tree topology

Tree topology is the combination of Bus and Star topology. Here the central workstation or the hub of the Star topologies is connected to the main Bus, along which various Star topologies are placed via their central workstation. If any particular workstation or the node is disrupted, then it will get isolated without affecting the network. But if the central hub of the Star topologies goes down then the whole section of workstation related to it also goes down.

Star topology

In Star topology every node (computer workstation or any other peripheral) is connected to central node called hub or switch. The switch is the server and the peripherals are the clients.

Ring topology

Ring topology is a network topology in which the nodes or the computers are connected in a closed loop. Each node is connected to two other nodes and when the data is sent it travels across all nodes in one particular direction. Ring topology is used when there is heavy flow of data as it has greater capability to handle data and doesn’t even require any central workstation to handle the data transmission.

Mesh Topology

Mesh topology uses one of the two arrangements either Full Mesh topology or Partial Mesh topology. In Full Mesh topology each node is connected to every other node in the network. In Partial Mesh topology every node is not connected to each node in the network. Due to many interconnections much of the cable is required for implementation of mesh topology so it is quite expensive. However, it is reliable because if one node fails, rests of the nodes continue to work with each other.

Bus Topology

Description, advantages and disadvantages of Bus Topology

Bus topology uses the single communication line called backbone which is shared by all the nodes or computers to communicate. It is used for smaller networks mainly and is one of the most simplest and reliable ways to communicate.
