What are advantages of using switches?

Advantages of Switching:

Switch increases the bandwidth of the network. It reduces the workload on individual PCs as it sends the information to only that device which has been addressed. It increases the overall performance of the network by reducing the traffic on the network.

What are the disadvantages of switch and hub?

Hubs are at a disadvantage against switches in networking because hubs are unable to differentiate between the devices on the network. If one computer is trying to reach another on a hub-based network, the computer will send the message to every other computer on the network, consuming bandwidth for each transfer.

What are the two disadvantages of circuit switching?

Disadvantages of circuit switching:

Doesn't use resources efficiently. Dedicated channels for circuit switching are unavailable for any other use. There is a higher cost to dedicate one channel per use.
