Answer:
Star topology
Step-by-step explanation:
Star topology : In a network,when different hosts(pc,laptops) are connected to a single communication point called server/hub/switch/computer.
Advantages of star topology :
- When a single node is failed,it will not affect the entire system,the other nodes work as earlier.
- We can add new nodes easily,without affecting the network.
- Monitoring of the network eases,as you can only check switch/hub for it.We don't have to check each node at the time of failure.
- Performance is better than other topology because the transfer of data is directly transferring from hub to a node.
- Less complexity of architecture of network.The central hub is connected to each node no node-node connections are there.
