A bus topology for a LAN will typically use coaxial cable, either 10Base5 (thicknet) or 10base2 (thin-net) copper wiring.
Topology refers to the physical method of wiring the devices to each other, what kind of connection devices are used, etc.

Well, yes. Please correct your question, thanks!

Copper is used for wiring!
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.
Answer: Star topology is commonly used in present days. It is used so much because it has more speed, and fast data transmission. It has one good quality that if one computer become out of order then no other computer experience any affacted.
