What is a network topologies
Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. Essentially, it is the topological structure of a network and may be depicted physically or logically.
Bus topology
This topology consists of a Backbone cable connecting all nodes on a network without intervening connectivity devices. The single cable is called Bus and can support only one channel for communication; as a result, every node shares the bus’s total capacity
Ring topology
In ring network, each node is connected to the two nearest nodes so that the entire network forms a circle. In a ring network, all the communication messages are transmitted clockwise in one direction, around the ring.
Star topologies
In the computer networking world the most commonly used topology in local area networking is the star topology. Star topologies can be implemented in home, offices or even in a building. All the computers in the star topologies are connected to central devices like hub, switch or router. The functionality of all these devices is different.
