5. Introduction
Network topology refers to the physical and logical arrangement of nodes
and connections in a network. It defines how devices are interconnected
and how data flows within the network. Understanding network topology is
essential for designing, managing, and troubleshooting networks.

7. BUS TOPOLOGY
Bus Topology: In a bus topology, devices are connected
along a single cable that runs from one end to the other. This
type of topology is cost-effective for large organizations as it
requires only a single cable. However, if the cable fails, the
entire network goes down

8. Bus Topology Cont…
- Advantages:
- Simple and easy to implement.
- Requires less cable length compared to other topologies.
- Cost-effective for small networks.
- Disadvantages:
- A single point of failure can disrupt the entire network.
- Limited scalability.
- Network performance can degrade as more devices are
added.

9. RING TOPOLOGY
Ring Topology: In a ring topology, nodes
are arranged in a circular pattern. Data
can travel in either one direction or both
directions around the ring. Only one
station on the network is allowed to send
data at a time, reducing the risk of packet
collision

10. Ring Topology Cont…
- Advantages:
- Data transfer is efficient, as each device has
access to the network.
- No collisions occur in data transmission.
- Relatively easy to install and expand.
- Disadvantages:
- Failure of a single device can disrupt the entire
network.
- Difficult to reconfigure and troubleshoot.
- Limited scalability.

11. STAR TOPOLOGY
Star Topology: In a star topology, every node in the network is
directly connected to a central hub. This central hub manages the
transmission of data and ensures that the network continues to
function even if a node goes down. Additional devices can be
easily added or modified without affecting the entire network

12. Star Topology Cont…
- Advantages:
- Easy to install and reconfigure.
- Failure of one device does not affect the entire network.
- Scalable, as new devices can be easily added.
- Disadvantages:
- Requires more cabling compared to bus topology.
-The central hub can become a bottleneck if it lacks sufficient
capacity.
- Higher implementation cost than bus topology.

13. TREE TOPOLOGY
Tree Topology: Tree topology is an extension of the bus or star
topology. Nodes are connected in a hierarchical manner, with all
nodes connected to a top node, creating a tree-like structure

14. Tree Topology Cont…
Advantages:
- Scalability and flexibility.
- Hierarchical structure that simplifies network management.
- Centralized control at the root node.
Disadvantages:
- Dependency on the root node: If it fails, the entire network can be affected.
- Performance may degrade as the network grows larger and deeper.
- Complex design and maintenance.

15. Mesh Topology
Mesh Topology: In a mesh topology, each node is connected to all other nodes, creating a
network channel. This type of topology provides redundancy and fault tolerance, as data
can be rerouted if one connection fails

16. Mesh Topology Cont…..
- Advantages:
- High reliability, as multiple paths are available for data
transmission.
- Fault tolerance, as the failure of a single link or node does not
affect the entire network.
- Excellent scalability and flexibility.
- Disadvantages:
- Complex and expensive to implement due to the high number of
connections.
- Requires more cabling compared to other topologies.
- Difficult to manage and troubleshoot.
