Network Topology is the physical and logical arrangement of the nodes and links in a Computer Network. Nodes are the compute devices that connect to the network and links are the medium that connect the nodes. The network topology depicts that structure of the network along with the nodes and links. Network Topology application of Graph Theory.
The physical topology is the physical connection of the nodes and links in the network topology.
The logical topology is the logical representation of the data flow between the nodes through the links in the network topology.
Each LAN technologies follows a unique Network Topology.
Types of Network Topology
Bus Topology connects all nodes in a line. The data flow happens between each node directly. Hub is example of Bus topology.
Star Topology connects all the nodes through a central node. The data flow happens through a central node. Switched Network is an example of Star topology.
Ring Topology connects all the nodes through a ring. The data flow happens through a ring. Each node has two peers. Token Rink Swit
Mesh Topology connects all the nodes through a mesh. Each node in the topology is connected to each other directly. Each node sends data to other node directly.
