Bus Topology | What Is Bus Topology? A In a LAN (Local Area Network), a bus topology is used when multiple nodes are connected to a single cable rather than a single backbone. Different devices are connected via a coaxial cable/RJ-45 connection. In a bus topology, if one of the cables fails, the entire network will fail. Alternate cables may be used for network security purposes. In comparison to other topologies, this is a very simple sort of network topology since it can be readily arranged.

Bus Topology In Computer Network:

In comparison to other types of topologies, bus topology in a computer network does not require additional connections throughout the installation. If one of the network’s nodes fails, the remaining nodes will continue to function. As a result, it is highly straightforward to add the most recent nodes to the network without delaying other nodes.

Due to data loss, this topology is not appropriate for long-distance networking. This type of topology will not work if the nodes are spread out in different directions, hence mesh, star, or ring topologies should be used instead.

As a result, this topology is suitable for short-distance networking. In comparison to a star topology, it requires less cables. The data transfer rate will be slowed if more devices are added to this architecture. Terminators are necessary on both sides of the cable. If an error occurs in this network topology, it is extremely difficult to discover and resolve the problem.

Bus topology diagram:

Bus Topology Diagram is as below.

One type of network topology is a bus topology. A single cable with a terminator is used at each end of this configuration. This one wire is quite beneficial for connecting all of the nodes that are currently available. There is no limit to how many nodes can be connected to a network, however these nodes will have an impact on network performance.

One of the nodes in this topology acts as a server, allowing data to be sent from one end to the other in a specific manner. The terminator will remove the data from the line once it reaches the endpoint.

Because this design holds the sent data through the cable, one large cable serves as the backbone for the entire network. When this data arrives at each node, the node will check the destination address to see if it matches their address or not.

The node will stop working if the destination address does not match. However, they process the data if the node’s destination address is the same as the address included within the data. The backbone cable in this topology is primarily determined by the network card installed on each computer. This card can be connected using either a coaxial cable or a network cable.

Examples of bus topology:

The following are some instances of bus topologies.

To connect two levels with a single line, a bus network typologies is employed.
An Ethernet network employs a bus network typologies.
One computer acts as a server, while the other acts as a client in this network arrangement.
The server’s primary function is to share data between different client PCs.
In companies or at home, a bus topology network is used to connect printers and I/O devices.

The bus topology is a simple design for connecting computers or peripherals in a linear fashion.
Simple to comprehend
It’s simple to expand this topology by connecting two cables.
When the network is small, this topology is effective.
This is a particularly cost-effective topology when compared to other topologies.
The needed wire length is smaller as compared to a star topology.
It is quite simple to connect or disconnect devices from the network without disrupting other devices.

Disadvantages of Bus topology:

The following are some of the drawbacks of bus network technic.

This type of architecture isn’t suitable for huge networks.
When compared to other topologies, this one is incredibly sluggish.
It’s difficult to figure out what’s wrong with the network.
Pocket loss is significant.
It’s difficult to troubleshoot each device’s problems.
If the cable is destroyed, the entire network will divide into two halves or be ruined.
Terminators are required at both ends of the cable.
When more devices are linked, the network becomes slower.
