Computer Network-Topologies

A Network we say it is an interconnection of many communicating entities which are connected for the purpose of data communication.The topology which describes the way in which networking devices are connected with each other.The physical topologies, in all the wires are interconnected, while logical topology it is how the network behaves and inter operates.

Various types of topologies like Star, Node, Bus, Ring, Mesh, Tree and Hybrid.The single node topology, which is just a single device called dumb terminal is connected to the server.While Bus topology connects each device to a single cable and at either end of the cable terminator which is used to remove unsent data from the cable.

While in star topology, multiple devices are connected with a central connection point which is known as hub or switch.Same way in a ring topology,data travels around the loop in one direction and passes through each device.A mesh topology, in which every device is connected to each & every node in the network with many redundant interconnections at least two paths to and from every node.

In the tree type of topology it connects multiple star networks to other star networks using bus topology.
