Topology describes how devices in a network are physically or logically connected. There are several common network topologies including star, bus, ring, mesh, tree, and hybrid. Each topology has advantages and disadvantages depending on factors like scalability, fault tolerance, cable requirements, and ease of configuration. A hybrid topology combines elements of different standard topologies to provide benefits while minimizing individual topology limitations.
Presentation on topology
- 1. Topology provides different configurations that are used to create a network Topology is a pattern of computers devices and describe the way in which these devices are connected Topology can be physical or logical Different types of topologies are Single node ,Star,Bus,Ring, Mesh,Treeand Hybrid
- 2. In a single node topology the server or host having all the information for the network
- 3. In bus topology, devices share a common cable to send and receive data. Server is connected at one end of the backbone cable and other devices are connected at different positions along the cable known as trunk Data is sent to all devices along the cable as the message arrives at each device ,it checks the destination address, encoded in the message. If the adders matches if accepts data. if not match device ignores the data
- 4. of bus topology: Easy to connect a device Requires less cable Work better for smaller networks of bus topology: Entries network gets affected if there is a break in the main cable Difficult to detect the fault device Heavy traffic and additional of devices degrades the performance
- 5. Multiple devices are connected to a central connection point known as hub or switch. Using copper or fiber optic cables devices are attached to the hub
- 6. Advantages and Disadvantages of star topology Easy to install, configure and manage Increased devices causes traffic which makes the network slow Easy to detect faulty device Requires more length than a linear topology Easier to expand Had failure leads to network failure Hud provides a centralized management More expensive
- 7. Each device is connected to adjacent devices forming a circle Data flow only in one direction ,clock or anti clock wise direction Each device is act as a repeater. it amplifies the signal transmission and transmits it to the next device
- 8. Dual ring topology consists of two concentric rings primary and secondary Primary ring carries data in one direction whereas secondary ring carries data in opposite direction Secondary ring is used if primary ring stops working
- 9. Advantages and Disadvantages of Ring topology Easier to manage as compared to bus network More cable wires compared to bus topology are required Handle a large volume of traffic One faulty device effect entire network Provides a good communication over a long distance Addition and charges of devices can effect the network
- 10. Each device is connected to each and every node in the network with redundant interconnections at least two paths to and form every node. Two types of mesh topologies 1.Fullmesh 2.Partial mesh in full mesh topology each device is connected directly to each other. In partial mesh topology some of the devices are connected to all the others
- 11. Advantages and disadvantages of mesh topology Provides redundant paths which help in sending data using an alternate path if a specific path fails to send data More cabling is required as compared to bus, star and ring topologies Entire network does not get affected by one faulty device Each link from one device to another requires an individual nic Centralized management is not requires as in star topology Very expensive as compared to bus, star and ring topologies Easy to detect the faulty device Difficult to reconfigure
- 12. A tree topology combines the characteristics of linear bus and star topology. Group of star networks are connected to the linear bus backbone Twisted pair cable is commonly used by tree topology Multiple such hub devices which are connected directly to a tree bus
- 13. Advantages and Disadvantages of tree topology Point to point wiring for each device More difficult to configure as compared to other topologies Easy to detect a fault device Fault in the backbone affects the entire network Easy to expand a network More expensive than other topologies
- 14. Hybrid topology is a combination of different network topologies The commonly used combination of topologies is star bus or star ring It has the ability to identify non operating devices and maintain the structure of the network bus or star ring
- 15. Advantages and Disadvantages of hybrid topology Useful for implementing larger network More cabling is required as compared to all other topologies Handles larger volume of traffic Mau( Multistation access unit) is required Easy to detect and remove faulty devices Installation and reconfiguration is difficult
