Types of Network Topologies with Examples
There are mainly six types of Network Topologies which are explained below. Network Topology examples are also given below.
Network Topology Types and Examples
The main types of topology are,
1.
Bus Topology
2.
Ring Topology
3.
Star Topology
4.
Mesh Topology
5.
TREE Topology
6.
Hybrid Topology
Bus Topology
It is the simplest network topology
among all topologies. In this topology, all computers and networking devices
are connected to a single Backbone Cable. In the below figure you can see the
diagram of Bus Topology.
In a bus topology, data can flow in one
direction only. Bust topology is the most cost-effective topology than other topologies
because of less cable required, and simple and easy installation,
administration.
Example of Bus Topology
The 10BASE-2 network is an example of
bus topology which is used in earlier days. Nowadays the bus topology is not
used.
Ring Topology
In the Ring Topology, all the computers
and networking devices are connected in a circular path or closed loop. The
last end of the network is connected to the first end. In the below figure, you
can see the diagram of the ring topology.
In the ring topology, the data
transmission is unidirectional. When data transmitted between two devices, the
data packet flows through all the nodes in the network so there is a chance of
data loss. Sometimes repeater is used in a ring topology to prevent and reduce
the data loss.
Example of Ring Topology
SONET Ring Network is an example of
Ring Topology. SONET stands for Synchronous Optical Network.
Star Topology
In the star topology, all the computers
and networking devices are connected to a single hub. This single hub act as
the central hub for all computers. You can see the diagram of star topology in
the below figure.
Data always transmits through the
central hub that means when a sender sends data, it will flow through the
central hub and goes to the receiver. The central hub in star topology act as a
repeater. The whole network depends upon the single hub. The central hub may be
a router or switch.
Example of Star Topology
Star topology is mostly used for
LAN(Local Area Network). In a small area, building, home, office, etc LAN
networking with star topology system is used.
Mesh Topology
In the Mesh Topology, all devices are
connected to each other so here a point to point connection is formed between
networking devices. In the below figure you can see the diagram of Mesh
Topology.
In the mesh topology, data transmission
is based on two techniques that are Routing and Flooding. Mesh topology is
classified into two types that are Partial-Mesh Topology and Full Mesh
Topology. Mesh topology required more cables that is why the cost of this
network topology is very high than other topologies.
Example of Mesh Topology
ALOHA, FabFi networking systems are the
example of Mesh Topology. The wireless connection between mobile, computers.
laptops can be said an example of mesh topology.
TREE Topology
The networking topology based on the
hierarchy technique is called Tree Topology. Here you can see the diagram of
Tree Topology in the below figure.
The Tree topology is best for wide area
network. Here adding and removing nodes are very easy and simple. The
administration process is also very simple. Fault can be found easily. The
management of the whole network is divided into each networking devices or
computer of that network.
Example of TREE Topology
Corporate Network mainly based on the
TREE Topology which helps to maintain the management system.
Hybrid Topology
When a network is made by mixing two or
more topologies then it is called Hybrid Topology. Here you can see the diagram
of the hybrid network topology in the below figure.
The largest network uses a hybrid
topology. The hybrid topology is very flexible and effective. The cost of the
whole network is very very high. The network is very complex in design. More
security system is needed in this topology system.
Example of Hybrid Topology
Our great INTERNET is an example of a
hybrid topology.
