Network topology is the arrangement of the various elements (links, nodes, etc.) of the computer network. Essentially it is the topological structure of the network. Topology is divided into two types Physical Topology (the placement of various components of a network, including device location and cable installation) and Logical Topology (the flow of data within the network).
Types of physical topology :
Bus Topology :
It is the 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 the message addressed to that device on the bus network.
RING Topology :
When each device is serially connected in a closed pattern with a single cable then the network system is called ring topology. As a rain crosses all the platforms to reach its destination, ring topology does the same to pass the message from one node to another node.
STAR Topology :
In this configuration, all nodes are connected to a central hub with separate 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 :
Tree topology looks like the branches of a tree where each and every node are connected with our parent’s node. It is also called by the name star+bus topology.
HYBRID Topology :
A hybrid topology is a combination of two or more different network topologies. This network is the mixture of both peers to peer and client-server networks. It can be either a wired or wireless network.
