Noun

datagram (plural datagrams)

  1. (networking) A packet of data passed across a network.
    • 1980 August 28, Jon Postel, “User Datagram Protocol”, in RFC Editor, →ISSN, RFC 768:
      The pseudo header conceptually prefixed to the UDP header contains the source address, the destination address, the protocol, and the UDP length. This information gives protection against misrouted datagrams.

Usage notes
  • Although the specifications of the Internet Protocol say that datagrams are what pass through the network, the word packet is more commonly used.
