Which of these best describes a bus topology?

A) The network is logically connected together into a circle

B) All nodes connect back to a central network device

C) All nodes are directly connected to all other nodes

D) A break anywhere can disable the entire network

E) It’s big and yellow (and perhaps even magic)

The answer: D) A break anywhere can disable the entire network

A bus topology is usually implemented as a single cable that connects device to device. This means that a break could separate the network into at least two pieces, and probably some of the clients would not be able to access their server. That probably explains why you don’t see many bus networks these days.

If you’re designing a network, you’ll probably use a number of different topology types. In this video, you’ll learn the advantages and disadvantages of some common network topologies.
