3. Introduction
Network topology is the arrangement of the elements (links,
nodes, etc.) of a communication network.
Network topology can be used to define or describe the
arrangement of various types of telecommunication
networks, including command and control radio networks,
industrial fieldbusses and computer networks.

4. Types of Network Topologies
Bus Topology
Ring Topology
Mesh Topology
Tree Topology
Star Topology
Hybrid Topology

5. Bus Topology
Bus topology is a type of network
topology where all devices are
connected to a single communication
line, known as a bus.
Data is transmitted along the bus from
one end to the other, and each device on
the bus receives every message
transmitted.
Only the intended recipient processes
the message, while the others ignore it.

6. Ring Topology
Ring topology is a type of network
topology in which devices are
connected in a closed loop or ring.
Data is transmitted in one direction
around the ring from one device to
another.
Each device in the ring acts as a
repeater, regenerating the signal before
passing it on to the next device.
It is reliable and provides high network
performance because data can travel
quickly in one direction.

7. Mesh Topology
Mesh topology is a type of network
topology in which each device is connected
to every other device in the network.
It can be implemented in a full mesh
topology or partial mesh topology.
It provides high redundancy and fault
tolerance because data can be rerouted
through multiple paths in case of a failure.
It is expensive and complex to implement
due to the large number of connections
required.

8. Tree Topology
A tree topology is a type of network
architecture in which devices are connected
in a hierarchical, tree-like structure.
In this, devices are arranged in a parent-child
relationship, with each child node connected
to a single parent node.
The tree structure typically has a root node
at the top, which has no parent, and multiple
leaf nodes at the bottom, which have no
children.
Examples of network protocols that use the
tree topology include Ethernet, Token Ring.

9. Star Topology
A star topology is a type of network
architecture in which all devices are
connected to a central hub or switch.
In this, each device has a dedicated point-
to-point connection to the central hub,
which acts as a traffic mediator and
broadcasts data to all connected devices.
It also provides an opportunity for easy
expansion, as new devices can be added to
the network by simply connecting them to
the central hub or switch.

10. Hybrid Topology
A hybrid topology is a type of network
architecture that combines two or more
types of topology to form a single
network.
This topology is created by connecting
two or more basic topologies, such as
star, bus, ring, or mesh, using a central
hub or switch.
It is commonly used in large networks,
such as enterprise networks, data
centers, and cloud computing
environments.
