Bus topology

Alternatively called line topology, bus topology is a network setup where each computer and network device is connected to a single cable or backbone. Depending on
the type of network card, a coaxial cable or an RJ-45 network cable is used to tie them together.

Bus topology was more common in the early days of networking, but other topologies, such as star and ring, are more popular today because they're reliable and easier to scale. Also, networks that utilize bus topology are susceptible to collisions, where two devices try to transmit at the same time, leading to corruption or non-transmission of data.

Bus topology still sees usage in scenarios involving smaller networks or as a segment of a larger network. Being less complex than other topologies, it is also useful in labs or classrooms for teaching students new to networking.
