Pros and Cons of different types of network topologies

Networking is the backbone of modern day businesses. Every business must define its networking infrastructure so that every unit of business must know how and why they are following a particular network structure. There are various types of networking structures but no one structure can be said to be the best or effective. Thus every type of network topologies has its own advantages and disadvantages.

Ring topology

The transmission of data takes place by token and data travels in one direction. Every node is connected to two nodes on each side. Nodes are connected in a way that make a close loop, hence the name ring topology.

Advantages

  • As information flows in single direction, therefore speed is better than any other topology.
  • Network server doesn’t need to control the connectivity among workstations.
  • Data flow and connectivity efficiency is very smooth that results in decreased collision.
  • Every system has equal access to resources every time.

Disadvantages

  • In ring, information and data is passed through source and destination that makes it slower.
  • Since ring is a closed loop, if any one node goes down then whole network will collapse.
  • The whole network is connected through wire connection so network is completely dependent on these connections.

Bus topology

The reason this type of network topology is called bus topology is because all computers or servers are connected to single cable wire. Every single workstation sends and receives signals through this single cable; the bus. It is a linear topology.

Advantages

  • Bus network is easy to extend and many other servers and systems can add in.
  • It is very cheap in terms of costing.
  • It is best for small network setup and effectively works for LAN.

Disadvantages

  • Whole network collapses if a single cable encounters some kind of problem.
  • Since all networks are connected to central cable bus then it becomes difficult to detect a problem in specific server or system.
  • Bus topology’s efficiency decreases when number or nodes increases in number.
  • Security is not very good as all computers receive same signal from the common bus.

Star topology

All computers are connected to central hub. In star topology, there is point to point connection as every system and server is connected individually and directly to the device. Every signal computer is controlled and regulated by the central hub or switch that enables the hub to act as a connection junction. It can work as repeater or signal booster as well.

Advantages

  • New devices can be connected easily and any device can be removed from the topology easily.
  • In star, the central junction controls and monitors all activities.
  • Since every node is individually and directly connected so problem in one device cannot affect the rest of the network.

Disadvantages

  • Network cost increases with the increased number of devices.
  • Capacity of central device is crucial that affects the performance of all the connected devices.
  • In this network, efficiency of all other devices is compromised if the hub junction is not capable of supporting that number of devices.
