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.

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.
