NETWORK TOPOLOGY

Network topology is the arrangement of the various elements {link nodes, etc.} of a computer network. Essentially it is the topological structure of a network and may be depicted physically or logically. Topologies are divided into two types one is physical topology and another id logical topology.

Physical topology is the placement of the various components of a network including devices location and cable installation while logical topology illustrates how data flow within a network, regardless of its physical design. There are 6 different types of physical topologies.

BUS TOPOLOGY - Bus topology is a network where all the nodes are connected with each other with a single common cable. When one node wants to access another node on the network then it puts a message addressed to that device on the bus.

RING TOPOLOGY - When each device is serially connected in a closed ring pattern with a single cable then the network system is called ring topology. As a train crosses all the platforms to reach its destination, ring topology does the same to pass a message from one node to another node.

STAR TOPOLOGY - In this configuration all nodes are connected Hub with separated cables. Here the central node or hub acts like the main server and the other nodes which are connected to the central node, act like client devices.

MESH TOPOLOGY - Here each and every network is interconnected with each other. It works independently. 

TREE TOPOLOGY - A tree topology looks like the branches of the tree where each and every nodes are connected with its parent's node. It is also called by the name star+bus topology. 

HYBRID TOPOLOGY - hybrid topology is the combination of two or more different network topologies. This network is a mixture of both peer-to-peer and client-server network. It can be either wired or wireless network.
