What is Topology? Types of Network Topology


Topology refers to the structure or shape of a network. That is, how the components of the network such as nodes are connected with each other, how they establish communication with each other. The word topology is actually derived from two Greek words topo and logy, where topo means place and logy means study.

On the other hand, if we understand it according to computer network, then a topology shows us how a network is physically connected and how is the logical flow of information in those networks. A topology primarily describes how devices are connected and interact with each other using communication links.

So then let us now know about what is topology, what are its different types and all the important information related to it.

What is network topology?

Network topology defines the layout, virtual shape or structure of the network not only physically but also logically. A network can have more than one physical and more than one logical topology at the same time.

Types of Network Topology

By the way, there are mainly two types of network topology.

  • Physical Topology
  • Logical Topology

Physical Topology

Physical Topology refers to how computers or nodes are connected with each other in a computer network. It is the arrangement of various elements (links, nodes, etc.), including device location and code installation of computer networks. In other words, we can say that it is the physical layout of nodes, workstations and cables in the network.

Logical Topology

One Logical Topology describes the way data flows from one computer to another. It is bound to a network protocol and defines how data is transferred across the network and which path it takes. In other words, it is the way the devices communicate internally.

physical topology Types of

here we now Physical Topology Learn about the different types of By the way, for your information, let me tell you that these are mainly of 6 types.

SL. NO Topology Types of Topology Definition of
1. Bus Topology In bus topology, all the network nodes and computers are connected to the same cable in the form of a queue in the same sequence.
2. Ring Topology In Ring Topology, all the computers are connected in a circular structure. Therefore, when connected to each other, they all depend on each other.
3. Star Topology A Host in Star Topology There is a computer, which connects to different computers and controls them.
4. Mesh Topology In Mesh Topology, each network node connects to some other network to form a mesh-like structure, due to which it is called Mesh Also called.
5. Tree Topology The structure of Tree Topology is a mixed structure, in which star topology and bus topology Characteristics of both are found. It has a main host computer like star topology and like bus topology all the local computers are connected by same cable in a certain order.
6. Hybrid Topology Hybrid topology is exactly as its name means in which two or more different types of topologies combine to form a mixed topology.

importance of network topology

Let us now know why Network Topology is so important after all :-

  • It plays a very important role in the proper functioning of the network.
  • It helps us to understand networking concepts better.
  • It is able to reduce operational and maintenance costs.
  • A network topology is a factor in determining the media type used for cabling a network.
  • Error or fault detection becomes easier by using network topology.
  • Through this, proper and effective use of resources and networking components is made.

How to know which topology is best for your network?

As such, no network topology is automatically the best. It depends on the location and the size of the network, what you can use there. Let us know about some things that you must know if you are choosing a network topology:-

  • cable length
  • cable type
  • price
  • Scalability

Cable Length

It has often been seen that the more cable is used in a network topology, the more work and cost it takes to setup it. Therefore, while bus and star topologies are very simple and lightweight, mesh networks are more complex.

Cable Type

Now you have to choose the type of cable that you want to install. Twisted-pair cables are more cost-effective, but have a lower bandwidth than coaxial cables. Whereas fiber-optic cables are much higher performing and faster. Can also transfer data but they are more expensive. In this case, you should choose the type of cable according to your need and budget.


Now let’s come to the cost, if you use complex network topology as well as expensive cables then you may have to pay a lot in this process. In such a situation, you have to decide which topology is right for you according to your need and budget, which will give you proper performance.


Now comes the turn of scalability, where you have to decide that whichever network topology you choose is suitable for your company. That is, whether you want to scale the network using that network topology or not. Means how easily you can change things. For example, in a ring network you have to take the entire network offline to manipulate any of the nodes, while in a star topology it is much easier to do so.

Each of the topologies discussed above has its advantages and disadvantages. Therefore, the key to building and configuring the right networking model is subjective. It is very important for any company to gather all the requirements and requirements before adopting a particular network topology.

Which topology is considered the best?

Full Mesh topology is considered the best. Well it also depends on your network and budget.

In which topology does the data transfer the fastest?

In star topology, data is transferred the fastest.

Which topology is the cheapest?

Bus topology is the cheapest.
