3. Network Topology
• Topology refers to the layout of connected devices on a network.
• A network topology is the arrangement of a network, including its
nodes and connecting lines.

4. The factors of a Topology
• Cost
• Flexibility
• Reliability
• Future growth
• Bandwidth capacity

5. Network Topology
• Mesh
• Star
• Bus
• Ring
• Tree
• Hybrid

6. The Star Topology

7. The Star Topology
• All nodes are connected to a central node by a single path.
• This is used for data processing and voice communication. networks
• Advantages
• Ease of service
• One device per connection
• Centralized control/Problem diagnosis
• Simple access protocols

8. The Star Topology
Disadvantages
• Long cable length
• Difficult to expand
• Central node dependency

9. The Bus Topology

10. The Bus Topology
• Popular topology for data network.
• Single transmission medium onto which various nodes are attached.
• Normally coaxial cable is used.
• Terminators at both end of BUS absorb signal, removing it from BUS.

11. The Bus Topology
Advantages
• Short cable length and simple wiring layout.
• Resilient Architecture.
• Easy to extend.
Disadvantages
• Fault diagnosis is difficult.
• Fault isolation is difficult.
• Repeater configuration.
• Nodes must be intelligent.

12. The Ring Topology

13. The Ring Topology
• A ring topology is a network configuration in which device connections
create a circular data path. Each networked device is connected to two
others, like points on a circle. Together, devices in a ring topology are
referred to as a ring network.

14. The Ring Topology
Advantages
• Short cable length
• No wiring closest space required
• Suitable for optical fibers
Disadvantages
• Node failure causes network failure
• Difficult to diagnose faults
• Network reconfiguration is difficult

15. The Tree Topology

16. The Tree Topology
• A tree topology combines characteristics of linear bus and star topologies
• A tree topology is a special type of structure in which many connected
elements are arranged like the branches of a tree.
• also known as Hybrid Topology.

17. The Tree Topology
Disadvantages
• Huge cabling is needed
• A lot of maintenance is needed
• backbone forms the point of failure.
Advantages
• Expansion of Network is possible and very easy.
• Error detection and correction is easy.
• If one segment is damaged, other segments are not affected.

18. The Mesh Topology
• A network setup where each computer and network device is
interconnected with one another, allowing for most transmissions to be
distributed, even if one of the connections go down.

19. The Mesh Topology
Advantages
• Each connection can carry its own data load.
• A fault is diagnosed easily.
• Provides security and privacy.
Disadvantages
• Installation and configuration are difficult.
• Cabling cost is more.

20. The Hybrid Topology
• A hybrid topology is a type of network topology that uses two or
more other network topologies, including bus topology,
mesh topology, ring topology, star topology, and tree topology.

21. The Hybrid Topology
Advantages
• Reliable
• Effective
• Flexible
Disadvantages
• Complexity
• Expensive
