What are the characteristics of the star topology?

In a star topology, each device connects to a central network connectivity device such as a hub, switch, or router. These devices would be connected as a "star" (points on a star).

The other characteristic of a star topology is that a failing connection will only affect the failed device unless that device is the connectivity device. This means that in most cases a failing device on a star will not take down the entire network.

Another characteristic of a star is that they are easily expandable and scalable.
