Data communications network in which data is divided into small segments known as packets. These are divided so that each packet forms part of a complete message that can be routed through a network of switches to its destination independently of all other packets forming the same message.

What happens in a packet switching network?

Packet Switching transmits data across digital networks by breaking it down into blocks or packets for more efficient transfer using various network devices. ... The network devices can then route the packets to the destination where the receiving device reassembles them for use.

What network uses packet switching?

Packet switching is most commonly seen on data networks, including LANs, WANs and the Internet. It is well suited to data transmission, as it allows networks to adapt to changing conditions quickly. For example, if one of the network's routers fails, packets can be automatically re-routed to avoid that device.
