Network Topology described the physical and logical relationship of nodes in a network, the schematic arrangements of the links and nodes or some hybrid combination thereof. The arrangement of hardware devices on a network with respect to internal security requirements and needs for public access is known as security topology. There are various types of network Topologies (physical) ,such as ; Bus topology, Tree topology, Mesh topology, and hybrid topology other than this , there can logical Topology for the network which refers to the relationship between nodes and logical connections defining the way of transfer of data.
Bus Topology:
The network arrangement where all devices share single communication line or cable but it may have problem while multiple host sending data at the same time. Here failure of one device doesn’t affect another but failure of communication line may stop functioning.
An example of bus topology is connecting two floors with a single line.
Star Topology:
All host are connected to central device by point connection with hub device. If the hub fails, connection of all hosts to other fails. You can see the example of star topology in airports, Hospitals.
Ring Topology:
Here each host machine is connected to exactly two other machines and create circular structure failure of any host results in failure of whole system.
The example of ring Topology is SONET ring.
Mesh Topology:
In this , a host is connected to one or multiple host. Example of mesh Topology is connection of regional telephone offices.
Tree Topology:
It is also called as hierarchical topology where it imitates as star topology but has properties of bus topology. Tree topology is useful for large areas such as big universities and hospitals.
Hybrid Topology:
A combination of two or more topology is hybrid topology. Star-ring and star-bus are most common example of hybrid topology.
So the network topology is an arrangement of several nodes. It contains switches, router, hubs. It is useful in data communication.
