Well, yes. Please correct your question, thanks!
star good luck on chapter 12!
The most commonly used physical network topology is the star topology. This design features a central device, such as a switch or hub, to which all other devices are connected. It is widely used in modern Ethernet networks due to its simplicity and ease of troubleshooting.

The most common LAN topology is that of a "star." In a star topology, each computer, or "node", is connected to a central hub. This is more reliable than a more classical "ring" topology, because a node failing will not bring down the entire network. A bus topology is arguably more reliable, but has poorer performance.

Star is a very popular design.
star topology. Because they include a centralized connection point; can easily be moved, isolated, or interconnected with other networks; they are, therefore, scalable. For this reason, and because of their fault tolerance, the star topology has become the most popular layout used in contemporary LANs.
A bus topology for a LAN will typically use coaxial cable, either 10Base5 (thicknet) or 10base2 (thin-net) copper wiring.
Ethernet is easily the most common topology having replaced token ring in the 90's. Simply because of it's ease of use with CAT5 cabling, cheap networking hardware and not needing any termination.
