Describe how packet-switching can increase the reliability of a network.

What will be an ideal response?

In a packet-switching network, messages to be sent over the network are first broken into small pieces known as packets, and these packets are sent independently to their final destination. If a message is broken into packets and the packets are transmitted independently, it is probable that at least part of the message will arrive at its destination, even if some failures occur within the network. If the recipient receives only part of the message, TCP software on his or her computer can acknowledge the partial message’s receipt and request retransmission from the sender.
