Advantages and Disadvantages of Network Topology of Its Kind

Topologi Jaringan
As someone who works on computer networks, are you familiar with network topology? Network topology is a schematic description of the network arrangement, connecting various nodes (sender and receiver) via connection paths. It really needs to be noted that basically network topology has advantages and disadvantages depending on its use.
We have discussed various things related to the surface topology of the network before for each type of network topology. However, now we will discuss the advantages and disadvantages of each network topology of various types.

Kelebihan dan Kekurangan Topologi Jaringan Bus

The first is the bus network topology. As a very simple topology, it turns out that even though it is relatively trivial, it also has its advantages, which are as follows:

  • Excess

The advantages of the bus topology are as follows:

  • It’s cost effective.
  • The cable required is the least compared to other network topologies.
  • Used in small networks.
  • Easy to understand.
  • Easy to expand combining two cables together.

However, it is clear that if there are advantages there must be disadvantages. The disadvantages of the bus topology are:

  • Lack
    • If the incoming cable fails then the entire network fails.
    • If network traffic is congested or there are more nodes, network performance decreases.
    • Cables have a limited length.
    • It is slower than ring topology.

Ring Topology

Next is the ring topology. The topology where one device can be connected to more than one device or more precisely 2 devices is more advanced than the bus network topology.
It is called a ring topology because it forms a ring as each computer is connected to another computer, with the last one connected to the first.
There are advantages and disadvantages of the ring topology that you should know before deciding to use it, which are as follows:
  • Excess
    • Transmitting network is not affected by high traffic or by adding more nodes, because only nodes that have tokens can transmit data.
    • Cheap to install and expand.
  • Lack
    • If there is a problem, the solution is quite difficult in a ring topology.
    • Adding or removing computers interferes with network activity.
    • The failure of one computer disrupts the entire network.

Mesh Topology

Next is the mesh topology. This topology can be said to be not very flexible, but for every device it is fully connected. You can say that the mesh topology has n(n-1)/2 physical channels to connect n devices.
Even though it looks flexible, there are also disadvantages as well as advantages. What are they?
  • Excess
    • Each connection can carry its own data load.
    • It’s strong.
    • Faults are diagnosed easily.
    • Provide security and privacy.
  • Lack
    • Difficult installation and configuration.
    • Cabling costs are more expensive.
    • Bulk cables are required.

Tree Topology

There is another tree topology. This topology, which is usually also called a hierarchical topology, must have at least three levels to the hierarchy.
This topology is indeed very suitable for the use of a large number of devices and also with a fairly large room. At least that’s what it’s used for, but apart from that the drawbacks also loom as well as the advantages.
  • Excess
    • The tree topology is an extension of the bus and star topologies.
    • Node expansion is possible and easy.
    • Easy to manage and maintain.
    • Error detection is easy.
  • Lack
    • Really need a lot of cables.
    • Because there are many cables, the guaranteed price for this topology will be expensive to manufacture.
    • If more nodes are added, maintenance becomes difficult.
    • If the central hub fails, then the network fails miserably.

Star Topology

For the topology that is still related to ring and mesh is star. In this type of topology all computers are connected to a hub via cables. This hub is the central node and all other nodes are connected to the central node.
The following are the advantages that you can get and also the disadvantages that you must understand in order to use this topology.
  • Excess
    • Fast performance with few nodes and low network traffic.
    • Hubs can be upgraded easily.
    • Easy to solve problems.
    • Easy to setup and modify.
    • Only affected nodes fail, other nodes can work smoothly.
  • Lack
    • Installation costs are high.
    • Expensive to use.
    • If the hub fails then the whole network is terminated because all nodes depend on the hub.
    • Performance is based on the hub depending on its capacity.

Hybrid Topology

And finally is the hybrid topology. This is a topology that can be said is the biggest topology in the world and one of them is the internet. Are there any drawbacks to the topology you always use? Of course there are drawbacks behind the advantages, what are those?

  • Excess
    • Reliable because fault detection and troubleshooting is easy.
    • Effective.
    • Scalable because size can be scaled easily.
    • Flexible.
  • Lack
    • Complex in design.
    • Expensive.


Each topology has its own advantages and disadvantages. This deficiency also does not mean it is not suitable for use, right? You need to know the summary above because when you want to create a network topology, you have to make sure which one is more appropriate for your conditions.
