Network Topology Types

Network Topology Types.

In this article, we will learn about Network Topology Types. The network topology is the plan of the various elements (links, nodes, etc) of a computer network.

Basically, it is the topological structure of a network and may be shown physically or logically.

Network Topology Types

Network Topology Types are:

  1. Ring Topology.
  2. Star Topology.
  3. Bus Topology.
  4. Tree Topology.

Ring Topology.

Ring Topology

This is topology forms point to point links (PPP – Point to Point Protocol) connecting computers in a closed loop. A single channel connects all the computers and there is no central computer in this topology.

Unidirectional links will allow transmission in one direction only (clockwise or anti-clockwise). The bi-directional ring allows trans mission in both directions, but one direction at a time.

The bi-directional link is better because, if a computer breaks down, the message is sent by the opposite ring towards the destination computer.

The data transfer rate ranges from 4 megabits per second to 100 Mbps depending on the channel selected for transmission.

Star Topology.

Star TopologyStar topology connects each mode with a central computer directly through a separate cable. All the transmission is made through the central computer so if the central breaks down the whole network goes down.

As separate cables are to be laid down, it is relatively expensive. The data transfer rate ranges from 1 Mbps to 100 Mbps depending on the channels used.

  Bus Topology.

Bus TopologyBus topology is the most simple and inexpensive of all the topology. A single cable runs to connect all the computer in this network.

The central computer controls the network, so any breakdown of the file server leads to the closing down of the whole network.

Data is transmitted to all the computer on the network, but it is received by the destination node only. The data transfer rate is between 1 Mbps to 50 Mbps depending on the channels used, with certain limitations.

 Tree Topology.Tree Topology

Tree topology is the hierarchical bus topology or the generalization of the bus topology. The node where one or more cables start for branching is called head end.

There could be many branches at the headed end, the branches could have more branches, for developing complex tree networks.

Data travels from every station before reaching the destination.
