Topology

The physical arrangement of Computers is called Topology OR the physicalConnectivity of different computers via different cables is called topology.Types of Topology1: Bus Topology 2: Ring Topology3 Star Topology4: Mesh TopologyBus TopologyIn Bus Topology all Computers on the Network are connected to a single cable called Bus. Coaxial cable is used in this topology. The bus topology is easy to install and the cost is usually lower then for other network topologies. But the cable failure shuts down the network, and it can be extremely difficult to locate broken cables on large Networks. Only one Computer can send the data at one time via bus. Data goes to every computer on the way of the destination computer.
Ring TopologyIn ring topology we connect all computers in the form of a ring with the help of a single coaxial cable. Last Computer is connected to first computer. Both way communications is possible. Ring topology is easy to install, but in the case of failure of any 1 computer all network get disconnect.Star TopologyIn star topology each computer is connected to a central device with its own dedicated cable. The central device is called Hub and Switch. Every computer can send the data at one time. Troubleshooting is easy .In the case of failure of any cable only one computer get disconnects.
Mesh TopologyIn mesh topology every computer is connected to every other computer in the network. A lot of cable is used in this network. Coaxial bale is used for connectivity.
