datagram definition

datagram

Self-contained packet of data that carries with it the source and destination information for correct routing. Datagram travels from a source computer (such as a website server) to a destination computer (client or user computer) via a packet-switched network (such as the internet), independent of any previous or subsequent communication between the two computers. The source computer need not establish a direct connection with the destination computer, and can send each data packet through any available route.
