Bus topology, also known as line topology, is a type of network topology in which all devices in the network are connected by one central RJ-45 network cable or coaxial cable. The single cable, where all data is transmitted between devices, is referred to as the bus, backbone, or trunk.
There are two types of bus topologies:
Linear bus topology. All devices are connected to a single cable with two end points.
Distributed bus topology. All devices are connected to a single cable that branches off into multiple sections, resulting in more than two end points.
Advantages of Bus Topology:
Works efficiently for small networks
Easy and cost-effective to install and add or remove devices
Doesn’t require as much cabling as alternative topologies
If one device fails, other devices are not impacted.
Disadvantages of Bus Topology:
If the cable is damaged, the entire network will fail or be split
Difficult to troubleshoot problems
Very slow and not ideal for larger networks
Requires terminators at both ends of the cable to prevent bouncing signals that cause interference
Adding more devices and more network traffic decreases the entire network’s performance
Low security due to all devices receiving the same signal from the source
