Topology refers to the layout of connected devices on a network. Here, some logical layout of topology.
- Mesh
- Star
- Ring
- Line
- Bus
- Tree
- Hybrid
MESH TOPOLOGY
They use dedicated links so each link can only carry its own data load. So the traffic problem can be avoided. It is robust. If anyone links get damaged it cannot affect others. It gives privacy and security. Fault identification and fault isolation are easy
STAR TOPOLOGY
Here each device has a dedicated point-to-point link to the central controller called “Hub”(Act as an Exchange). There is no direct traffic between devices. The transmission has occurred only through the central “hub”. When device 1 wants to send data to device 2; First sends the data to the hub. Which then relays the data to the other connected device...
BUS TOPOLOGY
A bus topology is multipoint. Here one long cable act as a backbone to link all the devices are connected to the backbone by drop lines and taps. Dropline- is the connection b/w the devices and the cable. Tap- is the splitter that cuts the main link. This allows only one device to transmit at a time.
