Bog'liq Chapter 4 Network Topologies Advantages of Ring topology - This type of network topology is very organized
- Performance is better than that of Bus topology
- No need for network server to control the connectivity between workstations
- Additional components do not affect the performance of network
- Each computer has equal access to resources
Disadvantages of Ring topology Star topology - Have connections to networked devices that “radiate” out form a common point
- Each networked device in star topology can access the media independently
- Have become the dominant topology type in contemporary LANs
- Stars have made buses and rings obsolete in LAN topologies
Star topology - Compared to Bus topology it gives far much better performance
- Easy to connect new nodes or devices
- Centralized management. It helps in monitoring the network
- Failure of one node or link doesn’t affect the rest of network
Disadvantages of star topology - If central device fails whole network goes down
- The use of hub, a router or a switch as central device increases the overall cost of the network
- Performance and as well number of nodes which can be added in such topology is depended on capacity of central device
Switched topology - A switch is a multiport, Data Link Layer device
- A switch “learns” Media Access Control addresses and stores them in an internal lookup table
- Temporary, switched paths are created between the frame’s originator and its intended recipient, and the frames are forwarded along the temporary path
- Switched topology features multiple connections to a switching hub/Switch
- Each port, and the device to which it connects, has its own dedicated bandwidth
