UTP- Unshielded twisted pair
Star topology is like the network is done by easily adding another network and the most common cable is used unshielded twisted pair cable. For the star topology purpose, Cat5 and Cat6 cable is used because it is an unshielded and shielded twisted pair cable.
ATM employs a linear bus or star topology which can work with fiber optics as well as twisted pair cable

A star topology is a method of connecting several computers to one another in a network. The cables used in a star topology are twisted pair cables or coaxial cables. Coaxial cables would be the cheapest solution.

star topology
Any topology can be used for a peer-to-peer network. The easiest is probably a star topology but it doesn't have to be.
Star topology.
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.
The "star" topology is the most common.
