Network Topology/ Types of Network Topology/ Categories of Network Topology

Today post is Network Topology 

In Network Topology Each computer system is a Topology is Called as Node. Network Topology Determined by the Configuration of connections b/w Nodes. In a fully connected network with N nodes, there are N(N-1)/2 direct links.

Network Topology are Clasiffied into 

> Bus Topology

> Mesh Topology

> Ring Topology

> Star Topology

> Tree Topology

Bus Topology : All nodes are connected in a single line

Mesh Topology : It contains at least 2 nodes 2 or more paths b/w them

Ring Topology : In this every node has exactly 2 branches connected. 

Star Topology : In this network nodes are connect to a central node

Tree Topology : In this network nodes are arranged as a tree
