a means of directing digitally encoded information in a communication network from its source to its destination, in which messages may be divided into smaller entities called packets, each of which travels independently through the network in paths based on moment to moment routing decisions made by the nodes through which they pass
communications network which divides transmissions into "packets" of information and send each "packet" separately over an open channel
Packet-switching is a method of sending computer data on telephone lines which automatically divides the data into short pieces in order to send it and puts it together again when it is received. A method of data transmission in which small blocks of data are transmitted rapidly over a channel dedicated to the connection only for the duration of the packet's transmission
