Bus topology, this type of topology is usually used in small-scale companies, because it has a simple topology and is easy to manage. This topology has a single cable throughout the network. While the cable that is stretched has a function for the main cable in this bus topology.

Explanation of Bus Topology
This network is a type of topology on a computer network that uses a single cable as the transmission medium or uses a central cable as the place where all devices, both servers and clients, are connected. In other words, this network is a type of topology that uses a single cable as the transmission medium to all devices connected to the server.
This computer network can be used to facilitate the connection of server and client devices in sharing data and information. Especially for one server that can provide services to a small number of clients, this bus topology is one that is highly recommended.
In this type of topology, each computer is connected to one long main cable, several terminals and the main cable is used as data traffic. That way this bus topology is rarely used in computer networks for certain reasons.
Definition of Topology
As a start, we will discuss what topology is, topology is a computer network that functions to connect two or more computers, a way to connect them requires several network topologies.
Previously, topology was a way of connecting a computer to another computer to form a network.
There are also many types of topology, but the point is the same, namely to connect two points on a network. Not only that, the topology also knows how each computer can communicate with each other.
The advantages of the bus topology
One of the advantages of a bus topology is that it is easy to manage and easy to maintain if there is damage, for more details:
Easy and simple
The bus topology is the simplest topology so its installation is fairly easy. For people who are new to network topology, they will not find it difficult when using a bus topology.
Has a Unique Design
For design, this bus topology is similar to the interior of a bus. So that this topology is somewhat unique, especially the layout section which is fairly simple.
Does Not Require Expensive Fees
Unlike other topologies, for example, hybrid which has a very high cost. So the bus topology is not too expensive in terms of installation.
This is because it does not require a large number of cables or components.
So that’s why this bus topology can be used without having to spend too much money.
Easy to Develop
Apart from not requiring a lot of money, it turns out that this has the advantage of being easy to develop. This bus topology also does not interfere with other network devices even though they are already connected.
Has No Effect On Other Devices
Even though there are some damages that often occur to client computer devices, you don’t need to worry when using this network topology. Because this topology is not affected by other client devices.
No Hardware Required
Apart from being very easy to use, the bus topology also does not require hardware such as switches or hubs like other topologies.
Disadvantages of Bus Topology
After the advantages above, then we will discuss some of the disadvantages of the following bus topology.
Hard to Detect Error
The first drawback of this technology is the difficulty of detecting when an error occurs. To overcome this you need expert IT staff so not everyone can handle it.
Has a Solid Data Transfer
This will make it denser when transferring data between computer devices.
Therefore this performance will get worse which will cause all other devices to suffer damage.
Access Speed Affects Other Devices
The speed of this topology can be affected by other devices, if one of the client computers must use a higher data access speed.
And also to strengthen the signal you need a repeater. In addition, the working principle of this network is that one computer is used as a server. Then for the network to be broken up using a cable connection, each computer network has a bus to serve as a connector.
Bus Topology Physical Characteristics
The physical characteristics include:
- Using the old technology which is connected by using one cable in one row.
- Not active to connect the computer.
- Each computer is not connected directly but is connected by a single cable which is the transmission medium.
- For data transmission using a single cable.
- The use of a terminator at the end of the cable is necessary in order to stop the signal from being reversed towards the other end.
- The end of the cable is attached to a 50 ohm connector.
- If even one cable is cut, the other computer cannot be connected.
- Difficult to analyze the problems that arise.
- There is no longer any technology support alias discontinued support.
How Bus Topology Works
The workings of this bus network topology can connect something to every computer on the network which is called a trunk segment. This bus can be called a cable that is connected between end to end which can be used to transfer signals from one end to the other.
At each end of the cable a terminator will be placed to identify where the data is being forwarded and also to absorb the signal.
If the terminator does not absorb the signal then the same signal will be sent back to the bus, which can disrupt the flow of all data. It is considered a passive network because all computer devices rely on transmitted signals.
