Network topology provides us with a way to configure the most optimum network design according to our requirements. Using network topology configuration is differentiated in many different types for the user to apply. It is also affected by various factors discussed in the presentation. Topics covered in this "What is Network Topology" video are: 1. What Is Network Topology? 2. Why Apply Network Topology? 3. Different Types of Topology 4. Point-to-point Topology 5. Bus Topology 6. Ring Topology 7. Star Topology 8. Tree Topology 9. Mesh Topology 10.Which Network Topology to Choose? What is Network Topology The Network Topology allows us to design our network-based by taking proper factors into consideration, such as installation, reliability, etc., which increases the work efficiency of the network and provides smooth transmission of data.

3. What Is Network Topology?
Network Topology, refers to the pattern or arrangement in which network devices and computer systems are
to be interconnected with each other. Network Topology is comprised of two parts:
 Network: It is often refer to as a node, which represent a computer or a device in the connection.
 Topology: This part refers to the pattern of the connection between multiple interconnected nodes.

5. Why Apply Network Topology?
Advantage in Network Connection: Using the concept of network topology in during connection of various
devices allows us to sketch a proper model of the whole connection helpful for security points.
Understanding Network Concept: Applying this concept also helps us to better understand the relationship
between various network devices and we understand the reason of this connection made in the network.

6. Different Types of Topology
According to the physical notation of connecting nodes(network devices) we can classify different types of
topology.
Types of Topology
Bus Topology
Ring Topology
Star Topology
Tree Topology
Mesh Topology

7. Point-to-Point Topology
 In this type of network connection, two hosts(Computer System/Network Devices) are connected through a
single line cable.
 With both hosts at the extreme end of the cable to share data and information.
Data Sharing
Host 1 Host 2

8. Bus Topology
 All the nodes(devices) in bus topology is connected to a single cable known as the network backbone.
 Sharing of data from any node reaches all the connected nodes, whether it was to be shared or not and the
end point is known as the Terminate Point.

9. Bus Topology
Advantages of Bus Topology:
 Easy Installation, due to simple cable configuration required it is easy to setup.
 Cost Effective, no extra network devices such as hub, switch needed, nodes are directly connected to the
cable.
 Prevent Network Failure, in case of single node failure other nodes are not damaged.
Easy Installation Prevent Net Failure
Cost Effective

10. Bus Topology
Disadvantages of Bus Topology:
 Complex Troubleshooting, due to the simple configuration, detecting error nodes becomes difficult.
 Network Interference, in case of multiple nodes share data, they crash into each other and destroys the
signal.
 Loss of Data, due to direct data exchange, loss of signal is quite high.

Troubleshooting Loss of Data
Network Interference

11. Ring Topology
Nodes
Clockwise Data
Movement
 As the name suggests the nodes in this topology are connected in a circular format forming a ring shape.
 The data flow is in clockwise format.
 Works on the method of token passing.

12. Ring Topology
Advantages of Ring Topology:
 Better Network Management, removing error devices becomes easier.
 Easy Installation, the required hardware are easily available and easy to setup.
 Cost Effective, no extra network devices such as hub, switch required as nodes are directly connected to
each other through cable.

13. Ring Topology
Disadvantages of Ring Topology:
 Network Crash, problem with single node leads to the crashing of whole topology.
 Slow Data Transfer, due to the unidirectional movement of the data, data movement is slow.
 Problem Troubleshooting, to identify faulty nodes, special equipment are needed, crashing the whole
network.
Network Crash Problem Troubleshooting
Slow Data Transfer

14. Star Topology
Nodes
Central Hub
 In this topology the nodes are connected through a central hub which can be a computer, or a network
device.
 The central unit is also termed as the server and the nodes as the client.
 Central unit comprises mostly of network devices for better data transmission in this network.

15. Star Topology
Advantages of Star Topology:
 Low Error Chance, due to connection of each node with central hub, error in single node does not affect
the whole connection.
 Easy Troubleshooting, through the central hub, troubleshooting problem in the connection becomes
easier.
 Efficient Speed, allows fast data transfer in the network.
Low Error Low Error
Troubleshooting

16. Star Topology
Disadvantages of Star Topology:
 Central Hub Failure, in case of problem with the central hub the whole network is shutdown.
 Connection issue with the network devices, as they need delicate configuration for installation.
Central Fail Complex Connection

17. Tree Topology
 Tree topology is a combination of star and bus topology.
 The node connection in the topology follows hierarchical pattern, with the topmost node as the root and
the branching nodes as the child nodes.
 They share data through root-child format in the network.

18. Tree Topology
Advantages of Tree Topology:
 Installing new extended network is easy in the network due to the star characteristic.
 Ease of troubleshooting error nodes increases the efficiency of the network and doesn’t affect the main
network.
Easy Installation Efficient

19. Tree Topology
Disadvantages of Tree Topology:
 Crash in central unit, in case of damage in the core part of the network, whole network connection is
crashed.
 Difficult to install security measures.
 Difficult in re-configuring the existing nodes.
Central Fail Complex Network
Security Measures

20. Mesh Topology
 Mesh topology, as the name suggests is composed of multiple repeated connection between the nodes
and share data.
 Can be divided in two formats:
 Full Mesh Topology: In this connection, each node is connected to every other node available in the
network.
 Partial Mesh Topology: In this some of the nodes are connected to all the other nodes in the network.
Interconnected
Nodes

21. Mesh Topology
Advantages of Mesh Topology:
 In case of damage in any of the node, does not affect the overall connection between the other nodes.
 High speed data transmission due to interconnected pattern.

Less Damage

22. Mesh Topology
Disadvantages of Mesh Topology:
 High cost, the connection nodes requires multiple cables and network devices for data transmission.
 Complex pattern, due to the interconnection of nodes, management of the network becomes difficult.
 Due to the repeated network connections, efficiency is decreased in the connection.
