Network Topology : 

Network Topology Topology refers to the shape of a network or the network’s layout. It is technique in which the end points or stations of a network are linked together. A topology basically defines how the network has to be designed and provides a structure to the network. Introduction to Computer Networks

Types of Network Topologies : 

Types of Network Topologies Introduction to Computer Networks Bus Topology Star & Tree Topology Ring Topology Mesh topology

Bus Topology : 

Bus Topology Commonly referred to as a linear bus, all the devices on a bus topology are connected by one single cable. Introduction to Computer Networks

Star & Tree Topology : 

Star & Tree Topology Introduction to Computer Networks The star topology is the most commonly used architecture in Ethernet LANs. When installed, the star topology resembles spokes in a bicycle wheel.

Ring Topology : 

Ring Topology Introduction to Computer Networks A frame travels around the ring, stopping at each node. If a node wants to transmit data, it adds the data as well as the destination address to the frame. The frame then continues around the ring until it finds the destination node, which takes the data out of the frame.

Mesh Topology : 

Mesh Topology The mesh topology connects all devices (nodes) to each other for redundancy and fault tolerance. It is used in WANs to interconnect LANs and for mission critical networks like those used by banks and financial institutions. Implementing the mesh topology is expensive and difficult.
