A method via which data is exchanged through a network between or among people or computers. Information is sent and received in blocks of information called packets. Each packet is routed individually through the network according to the most efficient
possible path at the time of its transit. At the destination, the packets are reassembled into the original signal. This scheme makes more efficient use of network resources than continuousconnection or single-path methods. However, when network usage is heavy, there can be a delay in the arrival of a sufficient number of packets
to produce an intelligible received signal.
