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.
Star topology
Star topology is one of the oldest topology
Star Topology
Star Topology, where Hubs can act as repeaters.
bus topology.
Scalability and reliabillty of star topology makes it the best, easy to remove or add a device.
Ring Topology, Mesh Topology, Bus Topology, Star Topology
star topology,bus topology,ring topology,mesh topology etc...
There are number of LAN technologies and each technology is classified into a category according to its topology , two such topologies are star and ring topology. In star topology ,The hub accepts data from a sender and delivers it to receiver, there is no security in star topology . In Ring topology Computers are connected in a circle- the first computer is cabled with the second computer.
