Explain the different network topologies
Answer:
Mesh Topology
-Mesh In a mesh topology, every device has a dedicated point-to-point link to every other device. The term dedicated means that the link carries traffic only between the two devices it connects.
-Node 1 must be connected to n - 1nodes, node 2 must be connected to n must be connected to n - 1 nodes. We need n (n - 1) physical links.
Star Topology
In a star topology, each device has a dedicated point-to-point link only to a central controller, usually called a hub.
-The devices are not directly linked to one another. Unlike a mesh topology, a star topology does not allow direct traffic between devices.
-The controller acts as an exchange: If one device wants to send data to another, it sends the data to the controller, which then relays the data to the other connected device.
Bus Topology
-A bus topology, on the other hand, is multipoint. One long cable acts as a backbone to link all the devices in a network.
Ring topology
-In a ring topology, each device has a dedicated point-to-point connection with only the two devices on either side of it. A signal is passed along the ring in one direction, from device to device, until it reaches its destination.
Hybrid Topology
A network can be hybrid. For example, we can have a main star topology with each branch connecting
several stations in a bus topology.
