Star topology:- In this topology all PC are connected with the central device. Central may be HUB and SWITCH. Star widely use in all over word. Ring topology:- In this ring topology all PC are connected in the frame of ring are close Ring topology use MSAU each PC has a two never road one is called up Stream and called down stream. It used token passing Matterhorn which implement the token ring network. " Is the best of star topology".

Mesh Topology... though if you use a beefy-enough machine in the middle, a Star topology might work.
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.
