# Network Topology is an Important Concept to Learn

Sharing is caring!

The layout of anything that forms part of a network in life is very important, because the layout would usually determine the relationship of the players involved.

We find layouts just about in anything in life, a good example of a layout is the layout of a game plan of soccer, football or basketball as well as baseball.

As a matter of fact, your layout is so important that if you don’t know how your layout is laid out or if you don’t have a layout for your ambitions then you will never achieve your ambitions and accomplish your dreams.

## In today’s article, we are going to talk about layouts

We are referring to the way that many of the computers that you use out there are able to connect to each other and form what we all know as a well-organized network topology.

The bulk of our conversation will be in and around network topologies, which refers to the layout of a network of connected computers or workstations.

A network topology determines how nodes in a network are connected to each other and the way that these nodes communicate, which is also determined by the network topology.

## The schematic description of the arrangement of a network

This includes its connecting lines and nodes are useful in guiding a network designers layout the communications of a network.

A network topology usually defines the geometry of a network; there are two features of a the geometry of a network that help network designers better design their networks.

The features are the physical topology of a network and the logical or signal topology of a network.

The physical topology of a network simply refers to arrangement of how the nodes, devices or computing hardware are laid out on a network.

The physical topology of a network gives network designers instructions as to how they should position their network devices physically in a room or a building.

## When a large network is being implemented or set up

You should know that there are many cables used when a large network is being implemented or set up in a big building, so having a good idea of how the information would flow through the network, can be helpful when setting your workstations and building the physical structure of your network.

The physical topology has its own standard designs, so you may want to know them in order that you may follow a design that has already been erected so that you don’t have as much of a headache setting up the designs of your network.

## The standard designs that exist already are

• The star network topology, which is laid out similar to how a star looks, but in this case the center of the star is a network server or a workstation.

## Star network topology

In the star network topology the workstations that would like to communicate to each other, would have to first go through the center of the star, which is a server or another workstation that is responsible for making the connection of all the workstations in a star network topology so that those workstations are able to communicate with each other.

In a star network topology all the workstations that are part of the network are connected to that central workstation.

A cable failure in a star network topology would not be that difficult to be able to identify, because the lay out of the star network topology will also help you to isolate the workstation that is linked to the central workstation through the failing cable and fix the problem.

Other workstations can continue to operate without being affected, and the workstation that is using the bad network cable to communicate in the network can be isolated and repaired or destroyed and purged out of the network if the cable of that same workstation was not the only problem.

## The one downside to the star network topology

The downside is that if the central workstation fails then the whole network can suffer through that failure because all the other workstations are connected to each other through the central workstation.

So if you are planning on designing a network at home or at your job and want to use the star network topology design, always remember that your central computer should be and has to be very much reliable, so that you don’t have to face the realities of a major system failure.

## The bus network topology

Another type of physical network topology is the bus network topology, which refers to a network that has the main cable as its central place where all the communication between the workstations is done.

The cable is called the bus and every workstation is directly connected to each other through a center cable, which means that their communication is not being handled or routed by another workstation, in other words, there is no middle man.

## The ring network topology

The ring network topology is another type of the physical network topology, this type of network topology mainly deals with workstations that are connected to each other in a closed loop, which forms the shape of a ring.

In this type of network topology, the workstation that is not linked to each other is able to communicate with each other using other workstations that are adjacent to them.

In a ring network topology workstations may be cut off from the network even if they are perfectly fine, due to other workstations not being able to work properly.

## The tree network topology

Another type of the physical network topology is the tree network topology, which is essentially used for large networks because in a tree network topology two or more star network topologies are connected to each other to communicate.

The tree network topology also uses the design from the bus network topology because a central cable is used to connect the two central workstations of a star network topology to form the tree network topology.

## The mesh network topology

The mesh network topology is another type of the physical network topology, and in this type of the physical network topology, either a full mesh or partial mesh schemes are used.

Workstations are directly connected to each other when you use a full mesh topology, and in a partial mesh network topology some workstation are connected to each other and others are not.

When you design your network make sure that you use a standard physical layout that is already available to you so that your network is stable and doesn’t crash, due to your inability to develop your own physical network design.

Network topologies have to not just be designed physically, but you should also consider the logical operations of your network as well.

## The logical topology of a network

The logical topology of a network will allow you to configure the way that the data that is being transmitted to the network is passed from one workstation to the other.

The physical connection of the workstations is not important when data is transmitted from one device to the other as long as all the hardware component (such as cables, workstations and servers) of the network work properly.

The paths the signals follow are usually what matters to the logical topology of a network; therefore, logical topologies of a network may force a star network to operate as a ring or a bus network if that is the best course for the network to avoid system failures.

## The architecture of the communication mechanism

The architecture of the communication mechanism of all the workstations in a network is defined during the logical topology development of your network.

You can use a network’s hardware devices to configure and maintain the logical topology of your network.

## The topology of a network is important

Before you set up your network make sure that you know what the physical and logical topology of that network will be, because the topology of a network is an important part of network design theory and if you do your homework well and understand the fundamentals of network topology you will be able to set up a network that runs smoothly all the time, not just sometimes.

Besides important network concepts can be better understood when you have a full grasp of what network topology is as well.

## Understand what network topology is

Some of you may even be able to set up a home network, without having the need to understand what network topology is or follow any of its standard designs.

But in a network there are always going to be obstacles and trouble that you have to anticipate and when they occur you have to be able to troubleshoot that network.

When you have a very good understanding of network topology, troubleshooting your network would be a piece of cake because you will know exactly where the problem would be and be able to quickly solve it.

Spending time on designing the network topology of your network will give you a better chance at building a network that is stable and many people will appreciate you for it, even when you are building a home network, because your family is important too and they want to be able to use your network swiftly and without any problem.

But you have to make sure that the network you design is stable and won’t crash on the users of that network, because if it crashes it will cause you to have a very bad experience fixing your network.

## When you design a network

Remember when you design a network you are the network designer and it is your job to make sure that your network is stable at all times.

The mathematical subject of Topology investigates objects whose characteristics are constant through distortion. Objects can be topologically equivalent while appearing physically different.

As an example, any two objects formed with a simple rubber band are topologically equivalent so long as the band is not parted. A noteworthy practical analysis technique based on Topology is Kirchoff circuit analysis.

## Computer Network Topology is an extension of basic Topology

This discipline examines the configuration of computer system elements and their associated interconnections.

Physical Network Topology emphasizes the hardware associated with the system including workstations, remote terminals, servers, and the associated wiring between assets. Logical Network Topology (also known as Signal Topology) emphasizes the representation of data flow between nodes, not dissimilar from Graph Theory analysis.

The logical topography of a network can be dynamically reconfigured when select network equipment, such as routers, is available.

Computer Network Topology brings inherent advantages and disadvantages to any system under study. Description of some of these advantages and disadvantages for several standard physical topologies has been provided in this paper. OR performance analysis studies do not solely focus on physical topology, but logical topology as well.

## Graph Theory provides a useful tool in prosecuting these analyses

This paper has provided several examples of analysis approaches for dealing with topologically related problems. Those areas covered included routing analysis, network sizing, and network corruption.

The techniques covered in this discussion can be adapted to related computer network applications.

Understanding of Computer Network Topology is fundamental to any network analysis effort, and may prevent wasted effort in the pursuit of less productive analysis approaches.

## Topologies are an important part of the network design theory

A better network can be built if you have the knowledge of these topologies and if you know the difference between each topology.

Similarly you should have the knowledge of each network device so that you can properly use them according to your network needs.

A misconfigured network can result in a waste of time and energy as well as a lots of troubleshooting methods, to resolve the issue.

So the basic understanding of the network topologies and network devices is a must to build a good network.
