datagram

[′dad·ə ‚gram]
(computer science)
A unit of information in the Internet Protocol (IP) containing both data and address information. In TCP/IP networks, datagrams are referred to as packets.

datagram

A self-contained, independent entity of data carrying sufficient information to be routed from the source to the destination computer without reliance on earlier exchanges between this source and destination computer and the transporting network.

See also connectionless, frame, packet.

datagram

The unit of data, or packet, transmitted in a TCP/IP network. Each datagram contains source and destination addresses and data. See TCP/IP and UDP.
