Networking (Types of Connection, RING TOPOLOGY) Part-2

In my previous post, I wrote about the Networking basic and MODES OF DATA TRANSMISSION. As I told that I would discuss about NETWORK TOPOLOGY, today I will write regarding NETWORK TOPOLOGY. However, before jumping to this topic, let us first look at ‘TYPES OF CONNECTIONS’. Mainly there are two types of connections.

1. Point to Point Connection,

2. Multidrop Connection


1. Point to Point Connection: It is a dedicated link connection. This type of connection is generally made to connect two computers. As a dedicated link connection, the entire capacity of the link is reserved for transmission between two devices.

2. Multipoint Connection: It is also known as MULTIDROP Connection. In this type of connection, two, or more than two devices share a common link. The capacity of the link is shared either permanently/specially or temporarily.

Now the types of connection part are over. So let us jump to the Network Topology portion. Let me first define the term ‘TOPOLOGY’. Topology means the arrangement or we can say the condition of one species in one geographical area. However, ‘Network Topology’ means “The way through which multiple numbers of computers are arranged in a particular order in a Network”. Different types of topologies are seen, but the most common of them are

  1. Ring Topology
  2. Multidrop or BUS Topology
  3. Star topology
  4. Tree Topology

Ok now I am writing about these topologies in detail with their own advantages and disadvantages.

Ring Topology: In this type of Topology, data is passed from one node to another in a series. Here each device has dedicated Point-to-Point connection, with only two devices present on either side of it. The signal passed through the ring is unidirectional in nature. A device can directly communicate with its two adjacent nodes and indirectly with other nodes. No MASTER NODE is present for controlling other nodes, so each device can take decision of its own. Each device present in Ring Topology is incorporated with a REPEATER. When a device receives a signal meant for the other node, its repeater regenerates the signal bit and passes it to the next node. This process continues until the data is not received by the destination device or node. Ring Topology is typically present in LAN connections.

Data flow in Ring Topology


  1. Easy to Install and Reconfigure
  2. Adding/deleting of devices require changing of only 2 connections
  3. More stable than other Topologies because of the absence of master node. That means data communication is not dependent upon a single central node or a single  communication  channel.
  4. Fault detection is simplified.


  1.  Unidirectional traffic
  2.  Communication delay is directly proportional to the number of nodes present in the Network. Therefore, addition of a new node delays the communication process.

For now I am writing about Ring Topology. Later on I’ll write on other topologies. So check back later. And don’t forget to leave your comments.
