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 according to the computer network, then a topology shows us how a network is physically connected and how the logical flow of information takes place in those networks. A topology mainly describes how devices are connected and interact with each other using communication links.
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 a network not only physically but also logically. A network can have one physical and more than one logical topology at the same time.
What do you understand by topology?
network topology It is called The method of connecting computers and data flow in it is called topology.
types of network topology
By the way, there are mainly two types of network topology.
physical topology
physical Topology refers to how computers or nodes are connected to each other in a computer network. It is the arrangement of various elements (links, nodes, etc.), including device location and code installation of a computer network. In other words, we can say that it is the physical layout of the 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 are now physical topology Learn about the different types of By the way, for your information, let me tell you that they 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 same order in the form of a queue. |
| 2. | Ring topology | In Ring Topology all the computers are connected in a circular structure. So they all depend on each other when connected with each other. |
| 3. | Star topology | In Star topology, there is a Host Computer, which connects to different computers and controls them. |
| 4. | mesh topology | In Mesh Topology, each network node connects to another network somewhere to form a mesh-like structure, due to which it 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. In this there is a main host computer like Star topology and like Bus Topology all the local computers are connected to the same cable in a certain order. |
| 6. | Hybrid topology | Hybrid Topology means exactly as per its name in which two or more different types of topologies are combined to form a mixed topology. |
Importance of Network Topology
Let us now know why Network Topology is so important after all: –
How to know which topology is best for your network?
In this way, any network topology is not the best by itself. It depends on the location and the size of the network that you can use there. Let us know about some things that you must know if you are choosing any network topology :-
Cable Length
It is often seen that the more cables are 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 they have less bandwidth than coaxial cables.
At the same time, fiber-optic cables are very high performing and can transfer data faster but they are more expensive. In this case, you should choose the type of cable according to your need and budget.
cost
Now it comes to cost, if you use complex network topology and also with costly cables then you may have to pay a lot in the process. In such a situation, you have to decide which topology is right for you according to your needs and budget, which will give you proper performance.
scalability
Now it comes to scalability, where you have to decide that whatever network topology you choose is suitable for your company. That is, if you want, you can 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 make changes to any of the nodes, whereas in a star topology this is much easier.
Each of the topologies discussed above has its own 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 needs before adopting a particular network topology.
Which topology is the cheapest?
The cheapest is the bus topology. It is very easy to build a network of bus topology and this topology takes advantage of the power of Macram.
Which is the best topology?
best topology star topology (Star Topology). Due to this, all the equipment and computers are connected to a central host which is also known as Host Note. Which is connected to the fiber optic cable of twisted paper, coaxial, cable and it acts like a server, and whatever information has to be given, it shares with this network.
Which is the most expensive topology?
Hybrid topology (Hybrid topology) is the most expensive network topology.
Which topology is considered the best?
Full Mesh topology has been considered the best. Well it also depends on your network and budget.
Which topology transfers data the fastest?
star topology Data is transferred the fastest.
Which topology is the cheapest?
bus topology It is the cheapest.
