4. Introduction
Network topologies describe the ways in which the elements of
a network are mapped. They describe the physical and logical
arrangement of the network nodes.

5. TopologyType
StarTopology
RingTopology
BusTopology
TreeTopology
MeshTopology

6. StarTopology
Star Topology is a network topology in which each network
component is physically connected to a central node such as
router, hub, or switch.
In a star topology, the central hub acts like a server and the
connecting nodes act like clients.

7. StarTopologyAdvantages & Disadvantages
Advantages
 Its speed is very high.
 Easy to install and reconfiguration.
The network is highly scalable.
Less expensive.
Disadvantages
It is very expensive. Maintenance cost is very high.
Failure of central hub will effect the entire network.
Performance is based on the single concentrator i.
e.hub.
Maintenance cost is very high.

8. RingTopology
Ring topology is a type of network configuration where devices are
connected in a circular manner, forming a closed loop.
In this setup, each device is connected to exactly two other devices,
creating a continuous pathway for data transmission.

9. RingTopologyAdvantages & Disadvantages
Advantages
The data transmission is high speed.
Easy to install and expand.
The possibility of collision is minimum.
Dependability.
Disadvantages
Less secure.
The failure of a single node in the network can cause the entire
network to fail.
Troubleshooting is difficult in this topology.

10. BusTopology
Bus topology is a specific kind of network topology in which all of
the various devices in the network are connected to a single cable
or line.
In general, the term refers to how various devices are set up in a
network.

11. BusTopologyAdvantages & Disadvantages
Advantages
Very cost effective as compared to other network
topology i.e. mesh and star.
Easy to expand by joining the two cables together.
Coaxial or twisted pair cables are mainly used.
It is easy to connect or remove devices in this
network without affecting any other device.
Disadvantages
If the main cable is damaged, the whole network fails .
This network topology is very slow as compared to other
topology.
Troubleshooting individual device issues is very hard.
Additional devices slow the network down.

12. TreeTopology
In a computer networking, tree topology is a type of network
topology that resembles a tree. In a tree topology, there is one
central node and each node is connected to the central node
through a single path. Nodes can be thought of as branches
coming off the trunk.

13. TreeTopology Advantages & Disadvantages
Advantages
It can support a large number of nodes.
It can be easily expanded.
Error detection and error correction are very easy in a tree
topology.
Disadvantages
It can be difficult to troubleshoot issues in a tree topology
as each node is connected to multiple other nodes.
The cost is high because of cabling.
If the central hub gets fails the entire system fails.

14. Mesh Topology
A mesh topology is a network setup where each computer
and network device is interconnected with one another.
This topology setup allows most transmission to be
distributed even if one of the connections goes down. It is
a topology commonly used for wireless networks.

15. MeshTopologyAdvantages & Disadvantages
Advantages
Capable of handling heavy traffic.
A single devices failure has no impact on
the network.
Provides privacy and security.
Data transmission is reliable.
Disadvantages
High price.
Significant duplicate connection risk.
Installation and reconnection is difficult.
