Network Topologies :

The design used for networking is called a Topology. There are two basic categories of network topologies;
- Physical topologies
- Logical topologies
The shape of the cabling layout used to link devices is called the physical topology of the network. This refers to the layout of cabling, the locations of nodes, and the interconnections between the nodes and the cabling.
A logical topology is the way that the signals act on the network media, or the way that the data passes through the network from one device to the next without regard to the physical interconnection of the devices.
The basic network topologies are;
1.Bus
2.Ring
3.Star
4.Mesh
5.Hybrid
