The bus topology network diagram is a simple example of network design and network collection where all computer devices are connected to one main central cable called the backbone. The backbone is the primary channel through which data flows, with a drop line for each computer that connects to it.
The diagram also shows that the backbone is terminated at both ends to avoid signal reflection, which could cause data transmission errors. This layout is simple and effective for small networks, making it a convenient choice when connecting multiple devices when designing your network architecture.
