Question

explain mesh topology, bus topology , star topology .

Answer 1

Explanation:

In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn't allow direct communication between devices, a device must have to communicate through hub.

Answer 2

Answer:

MESH TOPOLOGY =

• in mesh topology, each node is connected to every other node in the network
• and in this topology every node not only sends it's own signals, but also relays data from other nodes
• the overall cost of this network is extremely high as compared to other network topologies
• this type of topology can able to handle a large volume of traffic
• it is commonly used in wireless networks.

BUS TOPOLOGY=

• this topology is known as the backbone of the network
• it transmits data only in one direction
• there will be a central cable which joins all the computers in the system
• bus topology is also known as "linear topology "
• one of the computers in the network typically acts as a computer server that will provide data to all the clients
• this topology is used in small networks where cable requirements is relatively small.
• the main disadvantage of this topology is That if the main cable fails to work then the entire network becomes unstable
• because of this reason this topology is not used for large network

STAR TOPOLOGY =

• in this network each device is connected to central computer, generally server, using a point to point connection
• the central server acts as a hub
• it is popular because it's low startup cost
• it is very easy to add a new device to the network as only one cable us required and configuration is simple
• this network is user friendly and used in east way
• if anyone connection in the network fails, The other connection remain intact
• but if central hub fails then the entire network goes down

I hope u will understand my answer and it is helpful to u!!
