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.

star good luck on chapter 12!
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.
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.
he most commonly used network topology is a hybrid topology called the Star Bus TopologyRead more: http://wiki.answers.com/What_is_network_topology_and_give_an_example_of_the_most_common_network_topology#ixzz1TrCMGlb6
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.
Well, yes. Please correct your question, thanks!

Star is a very popular design.
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.
In a LAN, the star topology is very common.
