- 3. Introduction • Geometric arrangementof devices on a computer network, and the way they are connected to one another. • Defines the physical and logical interconnection between devices, and it determines how signals flow between them. • Often represented as graphs and use these network topology graphs to decide where to position each node and the best path for traffic flow.
- 4. Types of Network Topologies Devices areconnected to a common cable, which acts as a backbone for data transmission. Bus Topology A central device is connected to multiple devices, forming a shape of a star. Star Topology Devices are connected in a closed loop, and data travels in one direction Ring Topology A central device is connected to multiple devices, forming branches, creating a hierarchical structure. Tree Topology Every device is connected to every other device, providing multiple paths for data transmission. MeshTopology Combination of two or more topologies to form a new topology. Hybrid Topology
- 5. Star Topology • Ina star network, all devices are connected to a central hub or switch. • Each device has its own dedicated point-to-point link to the central hub. • The central computer is known as a server, and the peripheral devices attached to the server are known as clients. CENTRAL HUB WITH POINT-TO-POINT COMMUNICATION LINKS.

- 7. Bus Topology • Ina bus topology, all devices are connected to a single cable, known as the bus. • Data is transmitted along the bus in both directions. • The most common access method of the bus topologies is CSMA (Carrier Sense Multiple Access). COMMON TRANSMISSION MEDIUM FOR SMALL NETWORKS Bus Topology

- 9. Ring Topology • In aring network, devices are connected in a circular pattern and data travels in a single direction around the ring. • Each device acts as a repeater to pass the signal along to the next device. • The most common access method of the ring topology is token passing. CONTINUOUS DATA FLOW IN A SINGLE LOOP KNOWN AS ENDLESS LOOP Ring Topology

- 11. • Every deviceis connected to every other device, creating multiple paths for data to travel. • It does not contain the switch, hub or any central computer which acts as a central point of communication. • Mesh topology can be formed by using the formula: Number of cables = (n*(n-1))/2; THE TOPOLOGY OF WIRELESS NETWORKS WHERE EVERYONE IS INTER-CONNECTED Mesh Topology

- 13. • A central"root" node is connected to one or more other nodes, which are connected to additional nodes in a hierarchical manner. • There is only one path exists between two nodes for the data transmission. Thus, it forms a parent-child hierarchy. • Tree topology combines the characteristics of bus topology and star topology. THE TOPOLOGY OF LONG DISTANCE NETWORKS Tree Topology

- 15. • A hybridnetwork topology combines two or more of the other topologies to create a unique network design. • A Hybrid topology is a connection between different links and nodes to transfer the data. THE COMBINATION OF VARIOUS DIFFERENT TOPOLOGIES Hybrid Topology

- 17. Why is Network Topology Important? IMPORTANCE • Playsan essential role in how a network functions. • Makes it easier for network admins to locate faults, troubleshoot errors, and allocate resources across the network more effectively. • A vital source of information when diagnosing network issues.
- 18. CONCLUSION • The networktopology describes the network's structure of how all components are connected to one another. • The main factors to consider while selecting a network topology are the length of cable required, cable type, cost, and scalability. • Network configuration tools can help you configure your network correctly. • Network performance monitoring and troubleshooting software keep track of and notify users of network- related performance problems and outages.
